Head to head: Vortec vs Edelbrock

I've done my reasearch but wanted to get the opinion from you guys on head selection. I'm looking to up the hp on my stock crate engine I bought a couple of years ago. In its current form it's rated at 260, but I know a head and cam change will work wonders.

I have the option to buy a set of Vortec (906) heads & ( media blasted) Edelbrock RPM airgap (7516) intake to match. Cleaned, checked ,valve job done with upgraded valve springs 525-550. Price- $380. The other option is a set is Edelbrock EStreet heads 64cc 202 for $650.

Right now, im leaning towards the Edelbrocks, I'm currently running tpi using the Edelbrock hi-flo base plate and runners and I like the idea of having matched parts. Just add a Performer cam.
Thoughts?

If the Edelbrock's are more HP, I would go that way. No second guessing if the money is not the issue

Cost wise it'd be a wash. I'd have to get a carb, distributor, fuel pump etc. with the Vortec.

Re: Head to head: Vortec vs Edelbrock

I have an aluminum set of L98 heads I would sell!

I would say Eldelbrock though.

If you decide to go vortec, watch this video. It shows what is needed to make the votecs preform. I am sure you are already aware of the issues with running a decent sized cam on a stock cast vortec head.

Good luck with the motor. Sounds like it will be pretty healthy when you get done!

Re: Head to head: Vortec vs Edelbrock

ahhh..... forget the Eddie cam. It's antiquated design that produces little power considering the rough idle and poor off-idle power. Seems to be a grind left over from the 80's. There's much better available.

Re: Head to head: Vortec vs Edelbrock

When upgrading from a classic Chevrolet head design, it doesn't take a huge amount of work to make a difference with a nearly stock Vortec head. The expense gets higher when you start chasing 400+ hp. Installing a set of "cheater" springs and cutting the spring seats is a good starting point. The same trick has worked in many budget LT1 builds. Larger intake valves and bowl work is also a reasonable investment. The same changes to the exhaust side don't return as much power with a mild cam so many folks skip the hot side work. The E series heads are ok but you might want to think about how much power you're trying to build and how you want the truck to feel before investing in a larger street head. Sometimes the quest for more power, especially with a carburetor, takes a truck from "nice to drive" into PITA territory.

Re: Head to head: Vortec vs Edelbrock

I didn't get a chance to add that you can get a Vortec base plate for your TPI from Scoggin-Dickey. The TPI manifold isn't a great top end performer although you could invest in a FIRST system for up to 450 hp. Personally I'd stay with EFI on the Vortec's and I'd look around for a deal on a different intake.

I missed out on the original set but I did decide on the Vortec. I found another set though for a decent price that will need to be freshened up. I'm sticking with the tpi with the SD intake. What other camshaft would be recommended? The heads are stock & I don't want anything really radical. Just trying to bump the 260 hp motor up to 300+.

Re: Head to head: Vortec vs Edelbrock

There are plenty of good cams. I matched an lt4 HOT cam with L31 heads that had spring seats lowered, 2.02 / 1.50, and 1.6 rockers. It sounded good and was a very strong performer in the 400 hp range. Here's a thread with a similar build.
