O.k. Jim now I'm confused. I have attached a picture of the advertisment and circled the 5.0 Big Bore kit I mentioned in my other post. I was under the impression that it was a stroker motor. Please correct if I am wrong about this. I would also be greatful (And I think others would as well) if you could break down the differences between the big bore, stroker, and big bore-strokers. My motor is on borrowed time like all other supercharged cobras and I am trying to figure out how I want to go about rebuilding my shortblock.VTEngines said:are you sure you are talking about the same things??? The Big-bore is not a stroker....just a big bore. It uses a 3.700 sleeve with a stock stroke crank. It helps with upper RPM HP capability as the big bore helps unshroud the valves while the stock stroke reduces parasitic losses with higher RPMS. You will gain in both HP and TQ...but mainly just from the larger cubic inch displacement. A stroker is what you want for the big jump in torque. We do a 302ci stroker, a 304ci big bore and a monster 327ci big-bore stroker. Any questions feel free to e-mail or pm me.
Yes I am aware of what the ad said. The ad is actually what prompted me to call and inquire about their services. Basically what it came down to is me sending them my block and they would turn it into the big bore for $3500. The turn around time was quoted at 2 weeks as well.Mike Tymensky said:Razor,
The part that you circled is only a rotating assy (block and machine work not included). I can sell you the same thing except with a new romeo crank and balanced for $1779 + shipping, regardless if it's std. +.020 or a big bore. They don't have a stroker listed in their add. You will also notice that they specify stock steel crank.
BTW, I'm not trying to spam the board. I just think people need to look in more places. Most people don't realize that we are probably the cheapest out there. Especially when we don't sell used parts.

Also the #'s before the blower are probably from an optimized tune and exhaust.
.....you are correct, the final dyno numbers are with an optimized tune and exhaust. It really shows people just how important it is to get a proper re-tune whenever components are changed. Timing is so critical to making torque. I'm thinkin we need to take the Marauder to the next Hooter's burnout contest!!!
BTW, I still owe you and Scott a cold one.
Oh don't worry....i won't forget!
Very good point Mike.The other thing to think about, how often are you at high boost on the street? Most of the time you aren't. An engine pushing that kind of power/boost will normally just blow the tires off on the street.
