Hey guys been reading your threads great stuff!! I was wandering Can anyone build a reliable 496 from a stock 4bolt block using dart alm. heads 10.2 compression and still get 625 -650 hp @ 5000 rpm or so? I have a builder that claims he can, he is pretty well known in drag racing and he knows thers a big dif. in marine motors.I think he uses comp cams to guide him on cam selection.Im worried about reversion if its a big cam.Any thoughts? thanks
Talk to 10X (Frank)...he can tell you of many horror stories about unsuspecting guys like you who have taken their stuff to the wrong people.

[QUOTE=jeff1000man;2430650]He could get there with a cam set up for wet exhaust, he will have to spin it around 5500. I would use ovals though, or a realy small square port like no bigger than 310. Use a tunnel ram with dual 600's. You would need a header and use a solid roller cam, but I think it would work.
no access to the Swap Shop ????? and wtf is going on with that ???? you better sign up and be a OSO advertiser and Beanish will like you again

I bet sales have slowed down because I was buying most of that cr ap anyway.
You know anyone that has a full 14-71 set up with the intercooler that I can bolt right on. Carbs arrestor, snout, pulleys, belts, EVERYTHING. A 10-71 would work also, but I would rather have the 14.

Just service them and keep your eyes out for a deal on XR's
Or carry a 5/8 wrench in your pocket. JUST KIDDING

You don't need to sell your Bravo One drives. Either "Articfriends"/Smitty or "Mr. Gadgets"/Dick can take your existing Bravo One drive and make it into an XR drive by installing XR parts, blueprint the drive to the gearcase and even make it better/more reliable than getting a new XR out of the box.
