I have a question,my lt1 and the rearend is getting rebuilt this thursday,the shop is charging me 3800.00 bucks to rebuild the motor and rearend he said the car will push out at least 475hp....I was wondering with the amount of money im spending if it can buy 475 hp....the rearend is getting replaced from 3.23 to 3.73 the transmission was rebuilt 2 months ago and is pretty beefy but just let me now guys!!!!

 

i would get that in writing.what warranty does he give?

 

OK so maybe 600 to rebuild the rear end which leaves 3200 to rebuild your engine and give you an extra 200 horsepower over stock. Let us know if that actually happens.

 

$3200 is approaching what you would spend on heads, intake porting, valvetrain and gaskets, fluids, mailorder tune etc without any labor for that power level no shortblock work.

Basically if you can back out of this DO IT NOW because something is not right.

 

I doubt he will make those numbers. Ask him what will be done to the LT1.

 

If anything short of a large cam, heavily ported heads/intake, you arnt making 475hp no where.

 

Did he indicate the 475HP was at the flywheel, or at the rear wheels?

 

well fella's he says he nows the ''combanation'' to get that much power out of the motor,he said he had a 95 z28 that was pushing 475 and he said hes goin to do thee same work on my car as he did to his..........o and another thing i called up there today and asked them what kind of cooling system that they were goin to use they said that they were goin to use stock because what they are doin isnt goin to make that much heat.........WTF i now a radiator for a car pushing out that much power would b like 800 bucks but i can back out of it but i want to find some1 that isnt goin to f@3k me on my money.......how much can 3800 bucks buy u in horsepower?

 

forgot.....he said that he would give me a 12 month warrenty

 

You still didn't say whether he was going to make 475HP at the flywheel, or at the rear wheels. Seems like a simple question.

Stock cooling system shouldn't have a problem with a normally aspirated setup.

 

Ask him what he is doing to the heads, and what the cam specs are. Also is it going to be a 350,383 or 396.

 

hmmm....something doesnt sound right with that.

 

hes said the 475 would be at the flywheel

 

hmmmm . . . maybe I should take a drive up there and have him build me one too

 

475 Flywheel sounds right to me for 3200.. Thats like 390ish? I would just put used rear in which you can buy for as low as 150bucks!
