Re: 525sc's Rebuild
Yep - thanks mcollinstn a good brain workout is always healthy.
The B&M blowers were limited to 12k. Not sure about the Weiand. That was just an FYI. I had a ton of the B&M's over the years.

Re: 525sc's Rebuild
ok..here we go:
- dart / merlin perf. head/ valve assembly aprox 310cc
-mild additional porting
-8:1 comp ( bumped up over stock 7.5:1)
-454 @ 30over
-1050dom from 525sc
-stock intakes from 525sc
-original Gill exhaust
-rebuilt wiand 177's (stock 3'' pulleys)
-full hydrolic
-want to avoid water ingestion
-high reliability
-smooth idol
-5,200- max r's @ peak HP
-cruise 3,000-3,500
Which cam over the stock Crane #132561? Would the 731 be considered the next size up in terms of performance? Dont want more than i need. Only looking to add 75-100hp with heads and cam.
i promise to end this thread soon

We gonna have to charge you soon.Everything sounds fine, should work out well but make sure you dyno both engines and their fully dressed.

Re: 525sc's Rebuild
hydraulic roller conversion will cost a little $$. Figure $275 for the stick, $400 for the lifters, and $80 for the pushrods.
A good custom blower grind in a flat hydraulic will cost less, you'll use the same pushrods, and a box of $75 lifters. You'll have to go "one size bigger" on the duration to get to the same power level as the roller which will soften your bottom end a touch.
Just a thought (since you are on a budget).
