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.

Sent them to Holley in Calf, about $500 each
One was a little noiser than the other--came back the same way--but no problems so far.

L.S.

The Holley rebuild center isn't in CA, it's in Tenn. They charged me $550 to do one of mine last winter.

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

Re: 525sc's Rebuild
 

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).

Re: 525sc's Rebuild
 

When I get to my office tomorrow I'll check my bill.

Could have sworn it was Calf------ An I think it was a little less than $500

Re: 525sc's Rebuild
 

mc, think im gonna go for the full hydrolic, just dont know how different the crane 731 is from my existing stock cam. late yr 96' gen V 525sc.

Re: 525sc's Rebuild
 

RM, thanks for the specs. Which one do you think one be best for my set up??

Re: 525sc's Rebuild
 

The roller cam will make more power due to the higher lift and faster ramp speeds. Its probably worth about 20-30hp over the stock flat tappet cam and maybe more with better heads.

Re: 525sc's Rebuild
 

Your correct, just found the bill-- $475

Tenn. is where they are-- sorry for the error.
