I was looking at some speed pro cams for possible use in another sbc down the road.Looked at a couple with a lift of between 510 and 533.However, it says I can't use it with power brakes. Just wanting to build something around 10.5 to 1 and have some fun.
Wrong cam? Wrong brand? Go solid? Am running a XE268 with world heads in my other motor.

What is the duration at .050 as well as the CI of the motor.

Rick Wi; In ref: to your question:
Valve Lift Dur. adv. Dur.@.050 Lobe c/l
Int/Exh Int/Exh Int/Exh
.510 .510 318 318 244 244 108

With this cam I have 3-6 lbs. vacuum loss
.468 .480 304 287 220 231 110

Was looking at Crane cams also and didn't see anything about a brake issue with them.

Thanks...Jim

244 on 108 should be no problem, what converter, CI, gear?

350 sbc, bored .030.Run 456 or 488 gears..
Would like to try alum heads this time

4 speed, new M22.

Please consider either an Isky Z-25, -27 or -30 solid cam!!

The Z-30 can use 11 to 1 CR. real GOOD!!

Thanks pdq67, hadn't thought of that. That's got me interested, hmmm.

one of my friends has a .510 lift speed-pro and it seems to be good quality, sounds awesome too. he has had it for 2 years and no problem.

Sounds good Dave, do you know if he has power brakes? Any brake issues?

Speed Pro makes a quality cam. As for your Power Brakes, in a 350 anything more than 240 @ .050 is too much, IMO.

Id be happy with a 230 @ .050 in a 350, considering your gears http://www.nastyz28.com/ubb/biggrin.gif

he has power brakes and had to use a vacume cannister.

Re: Dave's 76..Thanks for the reply, that was my next question. Jegs makes a vacuum reserve system(so does Crane) looks like it would work.
Great, thanks for the input. I really like that Speed Pro 244.
Prob. easier to go with a Hyd cam instead of solid at this time.
