598 Engine Advise
 
I pulled the engine out of my 27' V bottom due to high oil consumption and poor leakdown numbers. I knew it had a Merlin block and Brodix heads and not much else. It has a 1050 Dominator with a Dart intake. The Dart is a 4100 manifold with a 4500 adaptor.
The heads are BB2x with 345 intakes. Turns out it is a tall deck, 4.5 stroke with 4.6 bore. Full roller cam etc. A nice suprise to find out its a 598. Any good reccomendations as to cam, compression etc? I want a reliable pump gas, 91 octane engine. Thanks in advance.

Look into super victor 4500 or sv565 for starters. That intake is killing you.

What exhaust are you running on it?

It has Imco Powerflows.

Compression 10:1 conservative., cam I will be like a MT and lay low. You should spec out and see what's in it currently though. A particular grind I would hate to say without proven certainty. The heads ported? You wanting to go hyd or solid roller? What rpm you want to run at wfo? Another words what outdrive you have?

I would like to stay with a roller cam. Not sure what I want for a max Rpm. It was thinking 5400. I have the weak link here, its a Bravo One drive currently. I baby it.

I have the perfect intake for that motor SV632 Edelbrock powder coated black nice no corrosion $350 pretty much half price. As far as a camshaft goes if you want the motor to be happy and 850hp right around 6,000 rpm at 10.0:1 compression you need a 273-275 intake high 280's exhaust @.050 113lsa works great the more lift the better. That cam with those heads and intake will pull like a freight train to almost 6,000 rpm and be all done by 6,200-6,300 rpm.
