So I am starting to plan out the Big Block build out for the truck and had some things I wanted to get opinions on.
Truck as it sits.....
Semi-recently Rebuilt 454 MKIV(less than 30K on it)
Rebuilt 3 speed trans
G80 Locker
Magnaflow Highflow cat
Magnaflow 24" muffler
3" pipe Cat Back
So this is the build plan I am looking at so far....
1. Comp Cam (something mild)
2. Edelbrock 3764 Performer 454 TBI Intake Manifold
3. exhaust ---Single pipe and no headers yet (I live in Cali so headers for CARB are too expensive right now)
4. Adjustable FPR
5. Stage 1 Chip ( I will tune it)
6. Open air intake
7. New Distributor....looking at an MSD
8. Cylinder Heads........????
So my question on heads that I am on the fence about is the heads... Right now its got Peanut port stock heads and I am debating on swapping to closed port heads to bump compression up some (roughly 9:1 would be target). Also what is involved in getting Vortec heads to work?
So looking at a set of 3964290 closed port heads but not sure yet.
3964290 1969-70 454 Closed 345, 360, 390 LS-5 100.9cc
So really looking for some feedback and suggestions on the build plan and some experience with different head choices. Thanks in advance.
