Hey guys i want to here your set up with your LT1. I would like to know how much power you are making and if you know your 1/4 mile time. I basically bought a LT1 from a 96 impala ss. I say basically bc they are holding it for me but its still in the car and they want all the money before they pull it. I dont like that deal. I was going to give them like 100 bucks then the rest once its done so i know all the wiring is good and not just cut. Any ideas? It is complete with everything for 500 bucks.
I know it is 260 hp and 330 tq. Why is that so much less than the camaro or corvettes? Should i get aluminum heads? What the difference in the engines? My goal with the engine is between 380-400 rwhp.
thanks

Im not exactly sure on the power difference. But a major role in it is most likely exhaust set up.

 

That's a good deal for that motor. The difference in the power from the impala and the f-body motor is the cams that they have, and the impala has iron heads which some say flow better than the aluminum ones. Just get a cam from an f-body or vette and the power will go up.

 

Ya it is complete with wiring and computer. I just dont want to give them all the money and they just cut all the wires to get it out fast u know. For my build i wanted to port and polish the heads to 2.02 and 1.6 have no clue how much money. Rebuild kit of course. 3000 stall with a hot cam mabey around .525-.550in lift. Then are the injectors big enough? Should i port out the TB to? Then headers and y-pipe. I'm hopin it wont be much over 3k.
thanks

Man thats pretty ambitious for 3K. Prob. looking at least 500$ for the head porting.Exhaust ran me about $600 for headers, y pipe and cat back stuff. You dont really mention a tranny, but I never could get mine to run well with the 700r4. You are gonna need some ecm tuning, so the service or the cable/software will be a couple hundred as well. I felt like I took a cheaper route and I still spent almost 7K. I guess it depends on how much you can do yourself.

 

with bolts ons and a six speed my car ran 13.4 @ 104 with a crappy 2.2 60ft time. That was when it dynoed 289 rwhp I believe.. 3395lbs. I was thrilled that day since it beat a then new BMW M3 in the other lane(not the v8 version).

with the current heads and cam etc.. it is over 400 but I don't really go to the track and it isn't why I put the car together but I could guess if it would ever hook low 12s or high 11s..

Good price on the engine but don't forget the formula, more power=cubic dollars.

 

My best time was 13.2 @ 106. That is with Hotcam, 1.6 rockers, LT4 KM, and full exhaust.

 

I want to be in the 12's. With my 3:73 and 3000 stall. I bought the motor last night! I pick it up thursday!

Has anyone tried this cam? What do you think about this cam?
Comp Cams XFI LT1 Camshaft, 230 / 236, .576 / .570 113 LSA, Strong mid-range and top end power. Headers, exhaust, gears, converter, computer tuning recommended.
or this one?
Comp Cams XFI Camshaft, 210 / 218, .560 / .555 113 LSA, Good low end, with strong mid range power. Headers, exhaust, computer tuning recommended.

good place to look for cam selection help is over on ltxtech or ls1tech

 

Or camaroz28.com in the lt1 section.. you don't need much to run 12's just some traction and a good stall.
