95 TBI Mods Help

[jdyates]

I would do the ultimate TBI mods, 454 injectors. custom tune. e-fans. All these are bolt on mods that will gain you some extra power. These aren't going to gain you big power. TBI heads are very restrictive so even switching to a carb will be a big letdown. What are your power goals?

Vortec heads ftw. Bolt-on and have immediate power gains.

I've seen the ultimate tbi mods and I'm soon going to get a custom tune once I put my cam in I'm also planning on swapping the heads to trick flow heads my power goals would be at least 300-400 hp I'm going to do a Eaton posi differential 3:73 or 4:10 gears Rebuild my tranny put corvette servo hays pro truck clutch kit not sure on the torque converter maybe 2000 stall then really focus on the motor maybe stroke it out to 383

Hey jd I actually wanted the vortec heads but people said if I do that might as well spend a little more on performance heads

I have a 454 t body on my truck , with a spacer you shouldn't have an issue . But you need the Inj plugs and tps plug

Yeah I wad going to say the tps connector is different and the injector plugs so the IAC valve is okay? &did you have to bore your intake?

It was done before I got it . I Could look later . A friend of mine did all the mods , I traded a 4wd s10 for my truck . I'm sure he didn't have the intake bored , he is to cheap . The way my truck is set up it beats my brothers 04 5.3 ecsb in a 1/8 mi street race .

Oh I see okay okay if I may ask what other mods do you have on your ride?

It's all in the sig I think . I may have missed some things , I have been changing out aftermarket for stock and going back and forth trying to get it to run right . I thought I was going to have to find a stock prom chip there for a while .

It's up to you. Summit sells fully assembled, ready to bolt-on Vortec heads for about $600-$700 per set. I found my #062 heads locally for $300, rebuilt, ported and polished.

EDIT: but theres a little more to it than that. The vortec heads will bolt directly to the block no problem, but they have 8 intake bolt holes instead of 12 like the TBI heads. You can either get the heads machined to add the missing tapped holes and use the stock intake, or you can spend an extra $200 for a carb intake with TBI adapter like I did, and there are adapters already made for the 2" bores on the 454 TBI, so you can kill 3 birds with one stone. Heads, intake, and 454 throttle body for about $200 plus the cost of head gasket kit and bolts and other small stuff.
