Need opinions

Post by Sbc4life » Mon Sep 09, 2019 1:00 pm

I’m currently building a 383 stroker in a 91 Chevy truck. Wanting to put Vortec heads on it with roller rockers.
Running a Lunati bootlegger cam. Not sure on lift and duration it was my cousins and he doesn’t have the specs.
Has a holly DP 650. I’ll be using a th350 trans with 3.73 or 4.11 gears. Would anyone think this setup would put rims 2017 Silverado with a tuned 6.2? Thanks guys

I would be Leary of running a used Cam unless you have heard the motor it came out from run and confirming all was quite and good!

Yea it was a brand new cam he actually installed it a while back. The motor actually runs but I’m changing a few things that he did and didn’t do. Like he went back with the factory heads for some reason. That’s why I wanted to rebuild a set of vortec heads for it and I also need to put headers on it as well

I guess you could say I’m building the top end. The bottom end is eagle crank and rods hyperputic pistons I believe

Your last sentence in your original post makes zero sense. Want to try again?

What type of cam? Flat tap or roller? If roller gonna use factory lifters? Awhile back I was considering one of those rollers but wanted to use factory lifters and think it was too much lift or something idk. I would think the cam has some part number on it.

I know as much as I can learn and try to keep an open mind to anything!

If I didn't overthink stuff I wouldn't be on speedtalk!

The Cam needs for a pickup truck especially a 4 wheel drive one with all its added power losses is a much different thing then one for a 3800 lb car,and changing out the Cam in a truck leaning over tall fenders is not much fun so I would try my damedest to find out the spec's on that Cam and change it if need be before the motor is in the truck.

It’s a hydraulic flat tappit cam. I’ll be putting a brand new set of roller rockers in. The heads still have the factory rocker arms. I know the cam is a 500 something lift. Might be to much for this setup
