244-248 Installed 4 deg advanced on 496 peak hp was 5,800 with hyd rollers and 6,000 with solid rollers tight lash. Not the same of course but just a for some reference.

wanna keep it below 5500 just to help the bravo live... but if 6K wont kill it... humm

Where did this supposed rpm limit of Bravo drives come from ? I keep asking about it, without any real answers ? If someone has some, post'm up.

between the clutch, the ujoints and other aspects of the design and the fact the factory rating was 5200 rpm...

its the big pony builds they don't like. Lugging, abuse, and hp is what gets most bravos unhappy. Rpm I've run 6k plus for miles on end. Suppose drive showers wouldn't hurt but the only one I lost was from a dead head in Lake Huron. And I mean lost as in on the bottom of the lake. 15 hrs on it if anyone wants to go drive diving.

Clutch is a simple contact of steel cones that are either engaged or disengaged. shifting in and out of gear at higher idle is what's hard on them and the driveshafts are pretty stout. You might be correct with factory rating due to warranties, etc but I failed reading owners manual in that department. Idling around with a drive in a trailer position is much harder on shaft that 6,500 would be.

well hell.. looks like I'm gunna be usin gen 4 **** got given a 4 bolt main low mile 454 with steel crank so now the real question since I don't have to source a gen 6 block and its lovely awesome roller cam setup do they do the 741 in a mk4 roller that's not some fubar almost 741 but not setup? or do I call comp and have em grind me one and if the crank is worth keeping what am I gunna give away I may want if I let the 454 spin 6k vs the stroker at 5300.. other than a damn prop ( which would suck being I got 3 28's to play with

crane cam you want is 139671,236/244 ls114,the old 741 on ls112 doesn't seem to be available.if you want ls112,a call to bullet should get you what you want.

Retrofit Gen IV Crane 139021 is 234/242 on 112; .610 / .632 - same as old '741' (139741)

actually,there was 2 741's,the whimpy 234degree intake and the massive power 236 degree intake,,both had 244 on the exhaust.bottom of the page racin always goes big.
