stroker life span?

slimjim said
On the last page I wrote that I average about 5-7k a year. If I knew the stroker wouldnt last that long it would probibly be about 4-5k a year. Streetable to me is simply being able to cruise around a parking lot without the motor "choking" as i look for a parking spot. what if I used the 3.71 in stroker camshaft instead of the 4 in? I think is 3.71 i may be wrong. Wouldnt it put me at 396 with a .03 over bore? That should last longer than a 416 right? You think I could get past 50k miles with that?

Not sure what you mean by "choking"... You mean loading up? Regardless of size and design they shouldnt be loading up on you if the tune's right and the driveline's matched to it. You're looking for 450hp at the crank. That can be done with a 360, but again, you will have some maintenance. So again, what is streetable to you? Do you have options like A/C or power brakes? Do you mind setting lash once a year? Do you mind running more expensive oils? Do you mind replacing valve springs or sending lifters out to be checked and rebuilt every two years? 450hp from a 3.75" stroke 440 is a performance rebuild with a decent set of heads and a cam. 450hp from a 4" stroke smallblock is the same but without the longevity. 450hp from a 360 or 340 is more radical and will need extra maintenance. I think if you "want it all" then perhaps the best choice would be a B 400 based 451, or just an RB 440. The 451 would be the best bang for your buck and the easier packaging. Except now you need to replace the radiator, mounts, headers, transmission and driveshft too. But, you can "do it once" and get a ton of miles from it while making the power you want and more.
