I'm curious to hear what other guys with the vortec heads are making for power. Post your engine specs and your numbers guys

mine are in my sig, I think I'm a bit slow though, hoping for low 13's this summer with better exhaust, tighter suspension and tuning.

:rockon:

 

Times are in my sig....but car will be getting a whole lot faster in about a month.....putting on Victor intake, bigger cam, and some real porting (didn't really do anything first time around). Hoping to hit 12.8 uncorrected. There's a .4 correction factor here.

'86 305
vortec heads, performer intake
XE274H cam
650 Holley DP
1-5/8" TES headers
3" cat & back
5 speed

13.5 @ 103.99

 

nice!
who else has some numbers on their vortec setup??

 

In my sig, the times were with 2.2 60' and stock timing tables from a caprice Lo5 eprom. I only had minor changes done to the fuel curve and have proof that my car was running lean above 5000rpm (fastest mph and lowest ET came from shifting before 5200). I've just got the 330ho crate motor with RPM intake and a shift kit in the tranny. Stock tcc, 3600 when raced with full tank of gas. Looking for a couple more mph and a 13.4 or 13.5 with some traction. Doing a cam swap in the summer, going to a roller of some sort, just don't know which one. Leaning towards the Lt4 hot cam but somebody told me the zz4 cam might be better for my setup (670 holley). Anything I do to bump the power is going to require a new fuel pump and a driveshaft loop so I don't know what's in store.

Specs are in my Reader's Ride profile:

I don't have bonified times, but I can beat my roommates 2000 Z-28.

 

With Vortec heads, dont you have to have a Vortec intake?

 

Yeah, what's the problem? There are like 6 or 7 intake manifolds for the vortec heads. Might not be a lot but they're all GREAT intakes, unlike 80% of the carb manifolds made for the standard heads.
Performer, Performer RPM, GM dual plane, GM truck EFI (looks like the LS1), Victor Jr, and I'm sure I'm forgetting one or 2.
They don't cost all that much more than a standard intake manifold.
