Well, I guess maybe not stumble across it, but I "MIGHT" be able to get ahold of this kind of money in the near future. This will be going into a thirdgen, but it is an LT1. I have the motor, and it is in good shape, but it is an impala motor. I think it has 104,000 on the clock. It has the vented opti(which I will replace). I was wondering what my best bet would be to do a complete build up of the motor. The cost doesnt have to include exhaust or anything like that. The wiring harness, accessories, MAF, and computer I have are actually out of a 95 T/A.

I was origionally thinking of a Forged 396, but I have read that you sacrifice either on the pistons or rod length to go this route. I was now thinking a forged 3??. Should I go with a stroker or just a 355. I was quoted 750 on all the machine work for the stroker. I was thinking that if I could go with a supercharger, I could lower the compression and run a good amount of boost with forged intearnals. I just need to know what parts to use and what is actually in this budget. I was figuring on one of the comp cam blower cam kits. From CMSMotorsports(I think this is the name of the company). There kit includes the springs rockers, cam and associated. I believe that kit is around 600. I think the blower kit its self is around 4000. I can build the motor myself, and install everything myself. I would like a set of AFR heads, but I believe that they run in the 2000 range and I dont have an unlimited budget.

Ok, so with what I have stated in mind, what do you think is a realistic goal for what I should get. Assume a 9000 dollar budget for long block and supercharger together. Is it doable and what parts should I use. The opti, exhaust and stuff like that will be covered by other sources of money so just worry about what I would need to get the actuall motor together.

Thanks

id go here

LT1 forged 383 fully assembled crate engine, with stage2 heads, custom cam, shipped for $5895.


then buy a clutch, and a 12 bolt rear end, and a wet nitrous kit.


HELLLLLLLO 10's !!!!

 

beat me to it

fuxer

Cmotorsports is GREAT idea.

I "stumbled" twice now...
see sig

ps-
where are u stumbling.. i dont seem to be falling as hard as you

 

If I went that route, what do you think it woudl run off the juice assuming I got the supporting parts needed and had it tuned? How do their heads flow?

Looks like i need to start saving up
Ahh, no job and still in school= i should have the money in no time

 

Well, I have a job, but I am in school also. I am trying to get a better job currently. The reason I might be able to do this is my brother has a 77 Trans Am Special edition. The motor needs gone through because it has a bad bearing(s). He said he would be willing to give me that and his 2 other cars(91 RS, and 78 280zx) for my 85 T/A because he doesnt have job right now, and cant afford to fix the T/A(other 2 cars are pretty beat up). My T/A that he wants has a built 350 w/ a 700R4 and 3000 stall with alum driveshaft and Borg Warner rear end.

The 77 T/A has pretty fresh paint, black leather, 6.6(400), and is the special edition like in smokey and the bandit. It was zebarted when new and doesnt have any rust. It has about 80,000 miles on it. If I fix the motor I could possibly get a good amount of money out of it.(Have a guy that would give 6000 for it now without fixing the motor) My brother claims that it is worth between 7000-1000 if I fixed it. I have been doing some checking and it appears that it may be worth that. We asked on a second gen site and was told that depending on condition it could be worth 5000, 10,000 or even more. I am still kind of skepticle about getting this amount of money for it, but if it turns out that it is acutally worth the money I plan on trading him and selling the 2 other cars to pay for freshening up/machining the motor and I will sell it and start in on the motor.

If I get this other job(suposidly I have a good shot at it), I should be able to afford to finnish the motor and buy another car to put it in. So as you see this could be a long shot, but if it works out I would like to have me a fast car. I mean, hte car I have now is quick, but you always want more right?!?!? The thing is, if I can make even 6000 off of that car, that is more that I could get for my thirdgen(I like them, but over all they dont seem to be a priority on peoples lists) and would cover the motor its self there. I have put a lot of work into the car though and I told him that I am not going to trade him unless it can be proven to me that I can make a good amount of money towards starting to build up my next car from this. This is why I had the "MIGHT" capitalized and in quotes in my first post, but I would like to know what I could afford if this works out for me. If not, I will have to slowly save up and build the LT1. Oh well, such is life. You guys wouldnt happen to know what a car like that would actually go for would you?

Lower the compression and turbocharge that ****! Turbos tend to give a MUCH better power curve than RPM dependent superchargers.

 

Any pics of your 85 TA? My first car and most favorite fbody out of all the gen's is the 84 TA. i absloutly love that body style.

 

Turbo's are nice, and I would like to go that route, but it seems to be a lot more expensive, and currently no one makes turbo headers for thirdgens so I would have to have them custom made. Also, I would tend to call turbo's a bit rpm dependant too. I havent driven a car with a centrifugal supercharger, but I have a 88 thunderbird turbocoupe that I used to drive daily.

As far as pics of my T/A I think I only have one good one online. I have some more good recent ones, but not online, and this board doesnt let you upload them. http://pic3.picturetrail.com/VOL25/9...8/19653089.jpg

I wouldn't use an LT1, thats for DAMN sure...
ehh maybe if if i was running turbo... MAYBE, but thats only because its the cheapest SPFI 350 you can really buy.. maybe a truck motor?

Reverse cooling is nice for boost.

 

Big cubes, big nitrous, small 1/4 times, smaller tire tread. The wise man has spoken.

 

Please elaborate. Why wouldnt you use an LT1? I would like the motor to see boost eventually.

 

I think a better answer is the following question

why use an LT1?

expensive parts, no real advantages- opti can prove to be a pain, intake manifold leaks...

Although they can call be taken care of, ehh i'd rather not

Go LS1 or TPI with alum heads and LT1 intake manifold

then again you can have SPFI with the LT1 over TPI..
i dunno tough call. I'm going LS1 next time around. i dont want to fiddle with 11s any more

 

The LT1 has a more advanced, easier to program computer than the TPI. The LS1 is friggen expensive to do a swap, and if I bought an LS1 car I doubt I would be able to afford to mod it. I was hoping that forced induction would take care of the problems with 11's.

MORE Performance sells some pretty cheap long blocks with a core. check them out at www.moreperformanceinc.com and see if they have some thing you like. they seem to build some pretty strong engines from what i've heard.
