LT1 N/A build
 

i recently bought a 79 t/a with an lt1

looks like it has cast iron heads

it was converted to carb and has a holley street dominator intake and carb and holley electric fuel pump, it also has an electric fan, no heat, no a/c
headers, x pipe and free flow mufflers


im curious to the hp/trq rating



over the summer i wanna get it to have around 375-400whp

heads/cam combo

any suggestions?

i was looking at 220cc heads, but i dont know what a good set up would be


also, a stall converter



im hoping to hit 12's

Personally I would say ditch those heads, try to find a set of aluminum heads, preferably castings 374s. I think. Have those heads sent to Lloyd Elliot or Advanced Induction and have them ported. Get a cam matched to the heads and your goals.
As for stall, I would say 3000 Vig or Yank, but I am not sure how much your car weighs and again, that will be needed for cam choice.

Not trying to be a dick, but are you sure it's an LT1 and not an LT-1?

Yea I was thinking the same thing

The LT1 used in the Impala SS and Caprice had cast iron heads so it could be one of those engines. I think they were rated at 260 hp.

:nod: My '94 Caprice had iron heads

Yeah, I know that, but it just seems a little odd that somebody would swap in a fuel injected LT1 with an opti just to convert it to a Gen I style setup...

yeah where is the distributor?

I would say its in the conventional place.

its from an impala or caprice, it has new style valve covers and its pretty clean

the 220cc's were aluminum

my car is 79 t/a, so it weights between 3700-3800

and the distributor is behind the intake on the right i think

im probly gonna go with the lt1-le1 heads and cam

thanks

Go LE2s, and a slightly larger cam.
And to be fair.

you have to build the bottom end for LE2 and it $450 more

Nope thats the LE3s your looking at, and I can't argue about the price change, but the LE2s can grow with your car if you decide to punch it out to a 355/383, juice, or forced induction.

Do you get spiffs or rep points for pushing LE products every chance you get?

There are other companies out there Besides LE

I wish, that would be cool.

i was planning on bolting on a pro-charger eventually, so that works

i was also looking at a tci streetfighter 700r4, says it'll handle 600hp

I would say look into Yank or Vigilante for torque converters, but that means I must work for them or something and get points for pushing their product.

tci has torque converters to match their transmissions

i just have no idea what my ratio is

3.43 or 3.73

he is like timmy

though you can't argue with the best.

So do you need a tranny too? Or do you just want the TC to match the tranny company wise?

i have a turbo 350, im pretty sure it wont be able to handle the power
and i want to convert to a 700r4 anyway
