Outlaw 190 Proof
Newbie
Hi everybody I have a 89 K2500 4x4 350 TBI with a TH400 ECLB truck that I am rebuilding and right now trying to make a decision on the engine build.
I know vortec or aftermarket heads would be the best but I don't have the money to do the vortec swap.
I just looked at the casting number of the heads on my 350 and it has 4102187 heads on it which I am pretty sure are 305 TBI heads with 58cc heads.
For my build my plan was originaly to gain compression ratio (9.5:1 at the most so I can run 87 octane)
port and polish stock heads and intake
ultimate TBI mods
keep my TBI spacer
new cam
any bottom end work needed
and reassemble with new felpros.
Question is now are the 187 heads better then the regular 350 tbi heads?
I have a edelbrock performer carb 2101 intake manifold and I am wondering it with these heads it would be a good idea to swap to carb. If I go carbed I know I need a regulator, distributor, coil, and carb.
The truck is just going to be a driver for long distance and my towing truck. It will be pushing 37s so torque is important and I am reading the TBI heads are good for that. I have another truck that is my DD so this one won't be driven much really.
thanks for any help
