nobody?

 

judging by the head flow numbers I assume this is for the 505?

 

yes this is for the 505, hoping for mid to low 11's

 

Heck, won't a good old CC 288AR solid street roller put you over 600 hp??

And right, UDHarold is the MAN!!

Paul, I wish you would actually build something using these old antique parts you keep recommending. I guess you have lots of time on your hands, but you never post results of ANYTHING.

 

Hey, some old parts are good.

 

Jason, I think you're not getting many responses because you never asked a question anywhere in your first post. What cam do you have now? Are the plans still for mostly street, or are you thinking more strip than street now? What heads are you running?

With 11 to 1 compression and 505 ci, you can go pretty big on the cam. Post some cams you're looking at and ask what the guys here think of them for your combo.

Ask VORTECPRO's opinion. I think he builds a 505, find out what cam he uses for that. Of course they work their magic on the heads, but whatever cam they use would probably make good power in yours also.

 

505, what it that 4.375 bore x 4.25 stroke? Not sure the effect of altitude on duration or LSA, I know it effects compression, but even at sea level I figure you would want about a 250 intake lobe. Looks like your heads stall at .600" lift on the intake side, but still continue to flow on the exhaust side. I think I would be looking into a solid flat with about .600 lift (based on a 1.7 rocker) and maybe set it up with 1.8 rockers.

 

oops well i just noticed that, umm lets see if i can remember the specs of the first cam off the top of my head, about .518 for lift duration seemed to be 275 advertised and about 218 @.050, i know its tiny for an 11:1 engine, but it runs decent around at our altitude, since the closest strip is over 100 miles away we still want it to have some street manners but are looking for more at the track, most cruises with it wont really be any more than 100 miles (that would even be pushing it) as we have the other el camino that gets much better mileage, as far as cams im looking at perhaps something in the 235-245@.050 range with about .550-575 for lift. Would like to keep the power brakes, but don't mind if they're a little hard. If i remember correctly VORTECPRO is running something similar to the Isky 280 Mega Cam (correct me if I'm wrong) What would you guys reccomend?

 

Jason,
I would be more then happy to work with you on your project but would need some additional info on the build and your goals for the engine. Drop me call and lets see what we can come up with.

 

There you go. Good honest advice from a great guy. Give Chris a call and get the right one and be done with it.

 

This is what I had in my 502 11.1 BBC chevy 638/638 -270/280 was a great cam pull to 7000 great solid. Its a comp cam listed in the catalog.

 

well we just had a few things come up at home and money is running a little tight, so any engine work is going to be put on the back burner for a few months, when I the funds present themselves i will definitely have to contact you Chris.
Thanks,
Jason

 

Jason, I think Chris is just talking about a cam for you. He can make you a custom cam based on your engine parts, compression, flow numbers, and stuff like that. It is definatley worth contacting him to see what he has to say about a cam for your particular combo.

 

Easy Bob!
Paul's perspective is as valued as yours in my opinion.

 

Chris, PM sent

 

The new voodoo 288/296 mechanical or the old UD grind from lunati or bullet.
It meets your requirements in a 468 so it should be fine in a 505.
