4 bolt main question?
I looking at the roush 402R 351 stroker motor. It makes 525 hp/500 'lbs torque. The motor comes with a 2 bolt main FMS block. Would the extra $1,500. for a Dart 4 bolt main block be a wise investment? I figure the boys at Roush know a lot more about performance engines than I do, but the 2 bolt mains are a concern.
Waddaya think?
