Re: 454 vs 496 vs 502
I scored like a 20,000 mile engine out of a motorhome 800 bucks like new... ported with 30 hours of finess and pain cut my 3 angle valve seats on the peanut port heads.. the bottom end was already decked like ten, 0.020 head gasket yielding like8.1:1 instead of 7.9:1.. took a lunati 60202, had it custom ground on a 108 LSA to get just under 7.4 DCR , Gets 15in of vacuum with 16degrees initial and a q-jet at say 700 rpm .. cheap regular street sized headers... There is your 500+ ft lbs of torque... here is a similar with junk peanut heads( unported) same cam on the 112 LSA on 8.8:1 compression dynoed:

Re: 454 vs 496 vs 502
We did run it on a dyno, if you go to my profile you can click on the album and there is a chart with the results. The final pull was 556hp 5400rpm and 606 ft/lbs 4400rpm. It's pretty much an old fart's pickup but you sure can surprise people once and awhile.

Re: 454 vs 496 vs 502
That sounds like a fun engine. I've been seriously considering building a 496. Would you be willing to share the basic info on the engine?

I would consider $5000 a good price for what you've got, all inclusive. Thanks for sharing.

Re: 454 vs 496 vs 502
Yes, thank you for sharing the info on your engine.
That helps those of us considering building a 496 in that we know a little more what it takes to achieve a given power goal.
