Default BBC 572 questions.

Hi
I'm building a BBC for my 64 Malibu and I have a couple off questions.
I need a cam for the engine and do not know where to turn I'm thinking Solid roller?? and I would also like to know what you guys think will it be a good combo? and I'm also interested in comments about the rocker are they any good?

spec.
Dart big M block 10.2" 4.5"bore
Jesel belt drive
Eagle 4.5"stroke
Eagle Hbeam rods L-19
JE pistons 8.5:1
AFR 357 heads
Jesel sportsman rockers
Bds intake
Kuhl 14-71
dual 1250 dominators

The engine will use pump gas and be a street/strip car

Gratefull for any advise!

thanx

I think that will be a killer street engine but if you are going to hit hard and often i would step up on the rocker arms i have ran the sportsman rockers and have broken those quit a few times.
also depends on how much spring pressure you are running

X2 spring pressure and cam lift.

I'm trying to find out what would be a good cam and when I know that I will know what springs to use.
I have a vision off under .800 lift but spring pressure is still a big ?


BTW

Will the Eagle parts be up for the task? I've heard that people say that they will hold 1500hp and I'm glad if i reach 1000hp so it should not be o problem right!?

Your list of parts is immpressive, the only thing I dont like is them weak Jesels.
I'd spring for some T/D's and be done with it.

Cams are not my fortay so keep at it on this one, there are guys on here that will chime in soon, be patient.

Eagle stuff is only a good as the final machining, double check everything or take it to your local machine shop and have them check it out.
Don't buy into their "fully internally balanced" selling point either - it's roughed in to say the least.
Pay the extra dough to get a good spin job, you'll be surprised how far out their "fully internally balanced" kits are.

After getting the green light on the machining and a good balance job it will handle 1K HP easy.

x2 on the eagle only being as good as the machine shop installing it.
Same goes with the jesel if they are installed correct they are fine, I've ran all versions of the jesel and all have been awesome. I always see t/d's breaking at the track and not jesel.

That's funny, I always see Jesel's breaking.
I've been running a used set of T/D's on my 496 for 2 years now - zero problems.

UDHAROLD would be the first person to find for a cam

cam king is also very respected here

comp cams Mr goldman is supposed to be verrrry knowledgeable.

if no luck with udharold or cam king here try speedtalk.com they should be there for sure

Thanx guys for the feedback.

The rotating assembly is NOT a balanced package. The machine shop that will be used has built several high horsepower engines so I trust the guys.

Ok, I'll be patient. I'm in no hurry because I will hopefully run next summer.
