Well, you're not the first one to say that. Like I told somebody earlier, my first hot motor build, looks like I overcammed like a lot of beginners? Im in the middle of reordering, tell me, is it a no brainer I should've stayed w 225/231, 500-510 lift, and if u have Summit catalog what is diff between Howards cl110245-12 and cl-110245-10. They are so close,wonder what 10 or 12 means. I know Im asking maybe obvious ques, I'll talk to Summit and my machinist tomorrow. Im going crazy. Truck has to be more than a Sat night special. I want fast but the old ladys gotta be able to drive it to store. What do u think>

[Jake Wade]

The difference is the LSA (lobe separation angle) 110, 112 .


I would suggest you consider the cam I posted in a link.

Compression ratio is important. Did you ever ask the builder the dish volume of the pistons he ordered?

[Old School Low]

Cant get ahold of hm this morn and i want to call summit to FINALIZE order. You sound like u know probably more than him. Lets say 9.4-9.6 CR. He told me one or the other one time when i asked. EVERYONE is saying .533 cam is too much. So...will u give me your recommendation of either Howards cams #110245-12 or110245-10 or113215-10. Do I want 10 or 12 separation? Or a whole other cam in tis price range.

[Old School Low]

Ill look for cam you pasted ...the other day?

[rs74]

I like the 292 dur. 488 lift cams myself.

This one with 1.5-1.52 rockers:

The 113215-08 would be an excellent choice for 9.4-9.5 CR also! Here is the link: http://www.summitracing.com/parts/hr...5-08/overview/

Still getting it all together. Im going to stay on this thread, I started 3 more when I first joined not knowing what I ws doing. (Can I delete others if I started them? How?) Caring people at this site contacted me when it was obvious I wasnt sure what to order for my 383. And I believe they were right. Had ordered WAY too much cam and ws cautioned aboutcheapo Pro Form rocker rollers. Today I ordered Howards 111145-10 Hyd Roll cam and lifters kit and went w 1.5 Scorpion rockers. Narrow, self aligning f or my Vortec heads. Machinist will work them for the added lift. Then the Weiand air gap and Summit 750 carb I'll keep. We have Chevy junk yard here in town where I found dip stick, timing chain cover and oil pan for $25 I think. Nobody wants to give me good response on ordering Summit carb but Ive got my fingers crossed that it will be the greatest carb ever built in the world. (according to Summit sales guy) I like the Jegs tall cast, center bolt valve covers for $83. Ill get new parts in 10? days and go from there. Highest 2wd Ive ever seen, dont like it, I'll get this engine done then flip rear and 2in drop spindle the front.

[Jake Wade]

The valve covers are NICE!

[Old School Low]

Went and visited my block today.

[Jake Wade]

I see they are the Speed Pro 12cc dish pistons, just right for the 3.75 stroke and Vortec heads.

[Old School Low]

good good

This morn on corner near my house. Sign says 1985, 454 w rebuilt AT and trans case. Needs tires. Id say 7-8 of 10 after walk around. Asking $9000. Not looking for myself and no idea what these are worth, just thought Id snap a pic. Last night got $10 junkyard grille on. After my son watched for days me and my little bitty nuts screws and washers trying to get fingers through grille and use new brackets i made, (hes a garage door installer who thinks self tappers are the answer to everything) he told me to get out of the way and in one minute its like its welded on. Thanks Chris.

[Sodell]

Glad you got the cam figured out, should make plenty of power

[Old School Low]

Good, thank you, I like hearing that.

[Old School Low]

Hey Low Echo, new 4ga positive batt to starter cable. Didnt fix it. The neg is only 18in long, loks perfect, it goes to alternator bracket. Another small wire from neg side is bolted to frame. You said 'block to frame'? is that something extra or do they all have that? (im learning) The two small wires on starter, one to big hot post w pos cable one goes somewhere else, they are dangerously close to header. I can now replace a starter in about 8 min.

[Old School Low]

Much help from this site kept me from overcamming for how I'll drive this truck. I have ordered Howards Retro Hyd Roller CL113215-10, it comes w lifters. 270-278 adv w .495/.500 lift. I sent back cheapo Pro Form roller rockers for Scorpion 1.5, self aligning, narrow body. Like a lot of novices I kept wanting alot of lift and lope but it has been explained to me this setup will get my truck movin on down the road just fine while being a totally streetable daily driver. If nothing comes off the heads CR will be 9.6 w the 64cc Vortecs.

[Old School Low]

After a lot of discussion w knowing people on this site here is what im going with for my first engine build. Today came the Howards Roller cl113215-10, .495/.500 w lifters, Pro Forms went back for these nice 1.5 Scorpion self aligning, narrow body rockers and the Summit dbl roller timing gear set up. Nothing too fancy, but with 3.40 ratio, it should get to the next light about as fast as I want to get there. Much work to be done on the truck itself but getting this done is about all I can handle at one time. It's a Heavy Half so sits a little higher than most, I cant wait to get top of fender wells down to at least the top of some slightly shorter tires...... Hey, trying to post a pic of parts on here and when I browse then clic upload, after a few seconds it keeps going to 'REQUEST TIME OUT, WAITING FOR AUTHORIZATION FROM CLIENT' Whats that about??

[Sodell]

Sounds like you have a plan coming together! I have good luck with photobucket for this sight....

[Old School Low]

Hmm, photobucket? If you dont mind elaborating a little, i'll try it. Computor wise (im not) relative might be here for Christmas, maybe she can help me.

[Low Elco]

Sorry it didn't help, fixed me right up. Usually there's a block to frame ground, then the block to battery. You pulled and cleaned all connections, incl. grounds and the mounting area for the starter and the bolts? Maybe just a weak starter. Sorry it didn't help. If it was out, did you get it load tested? Excited for your new engine.

[Old School Low]

I always like replies, thanks. Its 50% better, lol. Sounds EXACTLY like timing off, that hesitation, then it turns over good and starts. But ONLY when its warm, 2deg morn and it cranks over fast??? So screw that for now, i can live w it for another month when new engine goes in. Ill check or replace the little wires and everything. New problem yesterday. 2 tank gas valve switch. Messed up when I bought it, so IVe been pulling directly out of drivers side tank but pass side is 3/4 full so I want to use it up. Plumbed directly to it, ran for 10 min then no gas. That gs could be a year? old. No part store yesterday so just got Quad Jet filter, hope didnt plug fuel pump, does that ever happen? So in a minute I;; plumb back to drivers tank, change filter and I think Ill pull pass tank, drain it and maybe not even hook it up, Im scared now its all contaminted, 16gal is enough for me anyway, I like hot blonde at gas station too. Its 20deg and foggy, damp, (no garage) but Ill get out there in a little bit. Yeah, Im excited about new engine too. Guy building it off till Monday. I'll be posting. Dam! Just trtied to post u pic but it hasnt let me for past week? It says 'Request Time Out" whats that about? Edit----New starter did same thing so I put old one back in and save new one for 383

[hartbraker]

Your warm start hesitation is likely caused by your timing being slightly too far advanced. That is if you're absolutely sure that all of your grounds have good clean contact with the frame and block. Try easing off the timing ever so slightly and see if the problem persists. Let us know.

[Old School Low]

Thanks for the info, first thing tomorrow. We've 'sort of' tried this before but Ive got feeling that timing could still be the answer. 'Hand timing", we'd get it to start great but ZERO power or visa versa, Ill dbl check wires/grounds and tweek timing. An hour ago, new carb filter, back to drivers side tank and all good. Gonna take bad tank out and drain etc. This 350 motor is decent, Id give it to someone for rebuilding my th350. Any tranny guys around SE Wash state?
