What does everyone think about a 383 stroker in my TA? A friend mentioned it and it made me think. Give me some feedback! Thanks!

I think it would look much better in my TA

If that is as big as you want to go. I say yes..

Mike K.

do you need a new motor? new heads? that should all come into play because pending on your needs you may be able to go bigger than 383 for the same price.

the better question is what you think. its your car and more importantly your money. if it fits in with your plans for your car then by all means stroke it.

Hey JRP, how much HP (on the average) will a 383 stroker make? Thanks.

Blue Hawk

Depending on application (tranny, heads, cam, etc...), anywhere between 430 and 480 rwhp/rwtq.

The big benefit of a stroker is that it give you a much better curve over a H/C setup.

I hope to see 445rwhp/440rwtq on my 382 stroker (street setup with a very mild 224/.560/112+4 cam).

I love my Callies 383 forged stroker. No regrets at all.
477rwhp
440rwtq
just enough for a daily driver

With a stroker, you keep your old block with a just a .005 clean-up to obtain a 383 (3.903x4.000). Your stock heads can be ported (stage II). You only need bigger heads if you do an all-bore motor (stage III).

Basically a stroker package consist of forged crank, rods and pistons.

I saw that TSP had a LS1 block for only 600 bucks and the LS6 for 200 more. Will that work? Was thinking of going that route and buying the 383 kit (so i can still drive my car). Can you re-use any stock parts like Heads, Intake, Etc? Sorry to steal this guys thread but maybe he has the same questions..

Was gonna check out their web-site but it says comming soon in the f-body section.

I don't think it's worth it going to an LS6 block over your LS1 block. There will be no gain in HP and your LS1 block is actually strong enough to hold more power than any stroker kit can produce.

You can have you stock LS1 heads ported with bigger valves or buy some LS6 heads and have them ported as well (ported LS6 heads should give you 20rwhp over ported LS1 heads).

You must change your intake. With a stroker, an LS1 intake is a big restriction. At least, go with an LS6 intake or the new FAST intake with 78mm throttle body (more pricey but worth it with bigger cubes).

Other things to consider: 30lbs injectors, double-row timing chain, heavy duty oil pump, hardened pushrods... and of course a 12 bolts

As for the cam, most people here will go with 230 to 240 durations with 112 lsa for M6 and 114 for A4. It all depend on the applications. As I stated before, my cam will be very tiny (224/.560/112) compared to others but I'm after low and mid-range torque, reliability and driveability as my car is my daily driver. If you're looking for peak numbers, go with higher duration cams.

My car has 92K miles on it and it still runs good. Am gonna start Building a 383 as well. Might as well go bran new everything Block, Heads, Intake Etc..(will take 2-3 years if not more.) But might as well start now. How does a stroker motor handle a SC or a Turbo? Thanks

Blue Hawk

With a forged bottom end, a SC or turbo (or a big shot of nitrous ) should'nt be a problem!

A Forged bottom end? What exactly does that mean? Wouldnt mind after the motor is built to throw a SC on..

CHRISPY

I am going with a 385 stroker. No dropped sleeves and light alum block

With a six speed and stock rear should be anywhere from ~450/450 RWHP/RWTQ up to ~500RWHP/480RWTQ depending on cam, intake, exhaust combo.

Blue Hawk

The crankshaft, connecting rods and pistons that come in the stroker kit are forged. Those components are called the "bottom end" or "rotating assembly" of an engine. The stock crank, rods and pistons are cast, not forged.

The forging process compress the metal under very high pressure, making it more resistant. While the stock bottom end of an engine is good for "only" 600hp, a forged bottom end is supposed to be good for over 900hp!!!

And with a supercharged 383, you will see well over 600hp at the crank!

Ive seen 382,383, and 408 stroker kits and now 385 (sure there is more). Can all these be accoplished with the LS1 block? Is one better then the other? All same power?
