rwhp#'s for 347efi

looks like a neat forum guess i'll join in.

anyway here are some numbers for my 347 from about a week ago.no tuning yet but soon i will have a chip made for it on the dyno and tune from there.

408rwhp at 5800
392rwtq at 5200

Nice numbers... what are the ball park specs on the cam.

numbers are:
duration at .050.....240intake...230exhaust
lift..................576intake...544exhaust
lobe speration.......109

and yes those are correct it is biased toward the intake.

That would be a HiTech cam then...

Biasing the cam that way on a hotrod fuel injected Ford with a GOOD cylinder head and exhaust system probably isn't a bad idea.... I can see how it might work.

Most fuel injected intakes are more restrictive than their carbed counterparts, plus EFI engines seem to be more efficient and produce less exhaust.

They don't generally like a lot of overlap since it seems to screw with their electronic 'brains', but the reduced overlap provided by the lower exhaust numbers would help you get away with the larger intake lobe and tighter 109 degree LSA.

I like the way you think.... 'Outside' the box. [img]/phpBB/images/smiles/icon_smile.gif[/img]

Was any testing done with more conventional camshafts?

Good Luck!

mike...no other testing with other cams yet .this wednsday i will be taking it to get it tuned and by pass the revlimiter.hopefully it will pick up another 10rwhp.it runs excellent and is still very drivsable.i should have some 1/4 mile time on it by next wednsday also.

btw.it is a hitech cam.i wanted a cam that was biased considering the head i had on the engine and hitech specialized in them.
