i might get a 454 chevy pickup the engine has just been redone and it has a racing tranny and posi diff the only thing is that its not fuel injection...

does anyone have any advice on how to get this thing in running 12ss

 

What has all been done to the motor. Does it have a 350/400 turbo trans or 700r. What year is the truck..

 

What's it run now?

 

its an 1989 with a 454 it has a 400 in it but i test drove it today and felt really slow i guess am used to an ls1 it looks like i might have to get the engine redone....again...

 

if the heads are stock that is the big hold up on a GM big block. Check the heads and see what you have and if they are a stock castion toss them and go to the aftermarket. If it has a carb find someone what knows carbs and have them set it up. Just like FI if you dont have it set up right it will be SLOW. My carb was really rich out of the box but I thought it ran ok..I took it to someone who knows what they are doing and dropped down 2 jet sizes and swapped for a much smaller power valve it was like having a new engine pulled alot harder and ran much better. Good Luck

 

The stock heads for that year are peanut ports...119cc. Get some semi-closed or closed chamber heads (105 or 96cc). That will raise the compression from 8 to 1 up to 9.5-10 to 1. That combined with headers and a cam maybe something in the 560 to 580 lift range should get you close if you have the right converter.

i was just thinking of getting pulling it out and going with a 6.0 and new 4l60e i think i can make this set up run what i want and i know about it a little more. what do guys think. oh and do you need custom headers for this or can u use the ones for the newer trucks...

 

A 6.0 is not a bad way to go. I would think a 4l80e would be the better trans. But one thing, do not ever underestimate a big block!

 

get yourself a fuel injection kit from edelbrock or whatever if your not happy with carberators(yea i can't spell it). Heads and cam definetly.

 

The headers made for that truck would work...all big block heads have square exhaust ports save for a very few round ones or a heavily ported set. You can probably buy around $1000 worth of stuff to reach your goal vs $4-5k with the 6L swap. You could always swap the multi port injection from a 2000 big block truck.
