What do you think?

What do you think?

Post by rodney72 » Sat Oct 10, 2009 8:39 pm

Just wanted your opinion on this set up and if you think it will make the grade, i cant take any credit for it i bought it as is but interested if there is a weak link or something i should up grade.

CB 84 chevy journal crank
94mm mahle B+p's
CB 5.5 H beam rods
Manton push rods
Scat 1.4;1 pro rockers
CB 044 magnum heads.
44idf webbers.
Etc ect

What sort of HP could i expect if set up right.

You have a very similar set-up to me except I'm running slightly better flowing heads. (wedgeports)
A lot will depend on the cam you use and if you're after torque or bhp - I'm running a Webcam 86C with a rev ceiling of 7200rpm and a compression ration of 9.7:1

On the RACESHACK dyno which reads a little lower than most (due to it being a chassis dyno) it made 140bhp at the wheels (corrected that's 185-190 at the crank).

The most crucial thing to getting the full power is a dyno session with someone who knows what they're doing - worth every penny

Hi Orb,

Its fitted with a FK 7 eagle cam with a comp of 8.6.1? (whatever that is please excuse my ignorance) im thinking of taking it to Torque of the devil for a dynon session as raceshak is no more When i bought it there was talk of 160 BHP but that was never proved. Would like to have a bash at the 1/4 at santa pod this year.

160bhp is perfectly feasable, should make decent torque too which is more useful in a bus.
Let us know how you get on at the dyno and come and say hi if you're at Big Bang.
That should easily get you membership to the BWA, late 15, early 16 pace with that power :wink:
