Hi, I would like to do complete overhaul on my 1993 camaro LT-1 engine. So my question is: Which is better, to buy a standard rebuld kit, or stroker kit? I must mention that I have powerdyne supercharger and nitro installed, so I don't know if stroker kit is suitable for this setup. Could you please recommend me some websites where these complete kits are offered? And the last question: It's possible to rebulid LT1 camaro (2-bolt) to 4-bolt like Corvette?

Thanx

 

It's possible to rebulid LT1 camaro (2-bolt) to 4-bolt like Corvette?

Yes you can get 4 bolt splayed main caps and it will be much stronger then the corvette block (I sold my 4 bolt and went this way). It was $600 for the machine work, included boring the block .030 over, machine work for the caps and line boring and the ARP main bolts.
Here is a pic of my motor with the splayed mains

 

You might get more replys on this topic by posting it on LT1 Tech.

If you are already supercharged and use nitrous oxide, the 4-bolt conversion is probably a good idea!

 

Moving to LT1 Engine Tech.

You might want to add some details of your existing S/C and nitro(us) systems.... what kind of HP are we looking at?

 

Well, without knowing what kind of power you plan on pulling out of it, it's a little more difficult, but I have some off-the-cuff thoughts on it at this point.

If you were going to run it N/A with nitrous as the only power adder, then I would say definately stroke it out. More torque across the board with a marginal amount added to the cost for parts and clearance.

BUT, and this is a big but, your running a blower AND N2O. In that case, I would say go for the 4-bolts (pro-gram, milodon, others.. sell 4 bolt straight and splayed caps - machine shop makes the install happen) but don't bother stroking the motor out. Use the money you WOULD have spent on extra machining costs and put it in the pistons and rods.

I have a stroker kit from SCAT in mine, and the parts are very good quality. They sell all sorts of kits too. Cost on mine was very good, but I don't know about the others (such as Eagle, Howards, Ohio Crankshaft, etc..).

I'm sure others who know a lot more than me will chime in

Nitro - Edelbrock +80 HP
Supercharger - Powerdyne 6,5 PSI
SLP Headers, MAC cat, Borla

can you tell me, why the stroker kit is not the real deal for supercharged system?

Thanx for the advice and links indeed! I will chek it out.

 

Well, basically it boils down to bang for the buck. A stroker is always going to make more power in an N/A situation, but when you throw boost into the mix, all bets are off. A 1 psi increase in boost is going to give you more than 33 more cubes will. And if you build it to hold boost from the start by using the money where it does the most good (good pistons, rods, crank), then you can turn the boost up a LOT more than your 6 or so PSI, and make a heluva lot more. I would take a 355 (.030 over 350) running something like 10 -12 psi everytime over a stroker motor. Others will disagree I'm sure, but it's what I would choose to do, and I OWN a stroker motor. I just didn't have the additional 3K plus jack to add a blower onto it too, so I built to get the most out of what I have available.

You put together (or have it done) a 355 with somewhere near 10 psi (need specific blower pistons - IE thicker crown/ lower top ring land), and I can just about guarentee you will make somewhere north of 550 Flywheel. Getting the same thing out of a stroker N/A is difficult, and hard to live with everyday. Again, other will surely disagree, but thats cool too.

Simply put, I would spend the stroker money on other more important items to get the most out of the blower. If money is no object, then throw this advice out the window and build a bunch-o-cubes and THEN add boost. It's gonna cost more though when all is said and done..
