Starting to plan my first rebuild. got a 92 chev 1500 short box with a 350 tbi in it. It has 250k on it so im thinking a rebuild will do it good. My plan so far

refurbish stock tbi unit, get a throttlebody spacer and injector spacer

use stock heads i have the 193 swirl ports im pretty sure. Dont know if i should rebuild those or buy a new set? I was debating going vortecs and getting a intake to fit but i was talking to a guy and said its basically a waste to go with those heads unless i get a intake with 600-650 cfm. With it being my first rebuild i think ill try to keep cost down so maybe rebuilt 193's are the way to go?

bore the cylinders, get a set of flat top pistons and keep the piston to bore clearance tighter then a nuns......

get the deck milled .010 to up the compression a bit, I havnt really picked out a cam yet and undecided if i go roller or not. Will be putting on headers and exhaust system. install a AFPR also. Any thoughts or insight appreciated! Thanks

 

Toss the swirl ports , I wouldn't waste your money on a tb spacer or a injector pod spacer. Put your money into some vortec heads instead and 55#hr injectors mild cam and a new prom for your ecm.

 

alright so swirl ports are garbage. If i get a set of vortec heads this intake?

then will need this

seem about right? then just run the stock tbi on top of all that?

 

That maybe to high to fit under your stock hood.

its a cowl hood so should have some extra room. its a 454 clone if you will. and the stock tbi will have enough cfm to get the most out of those heads?

alright so game plan,

vortec heads
new intake either the gm performance tbi intake or a another carb intake and get an adapter plate for it.

some flat top pistons.

afpr and rebuild the tbi unit and run 13.5 psi

headers and run 2 - 2 1/2 exhaust

some mild cam not sure on what word work still learning reading up on them

and of course a new prom. then ill worry about the gears and tranny :P and get the deck milled for up'd compression.

thoughts on that? would a 454 tbi unit bolt on to all that no problem? wondering if i should up it to that and install 454 injectors to it......

thanks in advance!

 

any body got any thoughts....?
