Help me with this engine delima.. please
 

I am thinking about a 347 this time instead of the 306 BUT i need a CAMSHAFT the heads flow really well.. victorJr 750 carb. what cam do you guys reccomend to put this thing back in the mid 11's on Motor and mid 10's on the sauce? and how much more power will that 347 make over the 306?? or is it just torque? help me out here guys i am stuck//

Well, I am helping my friend build a 347 motor (EFI). He called Jim Cook ( www.lunati.com ) and Jim recomended a strong cam for him (part number 51014). Just tell Jim what you are looking for and what you have and he can set you up. Even if you don't want a lunati cam, you can take the specs on that cam and find you one with similar specs... Hope this helps.

had lunati, went with comp.
 

that 51014 is a little mild for a carb'd car. I was running a lunati 51018 and it was strong, BUT the dyno showed valve float(power loss) over 6200 rpm.

Id choose, and have chosen for myself, a comp cam 31-762-9

Im running a 347, stage 3 dart jr's, hooker super comps 1 3/4 primaries, 750 B&G carb and vic. jr intake. we made 430.8 rwhp with that combo<<<<<<<---- LOL still trying to get it to hook. but it runs well, i shift at 6800 rpm and rev limiter is set at 7200.

If you don't mind the extra cash I would go with a solid roller. Mine is a comp solid for a blower or nitrous (114lsa) and it still will do 11's on the motor all day. I love my cam the driveability is great and the idle sounds wicked. If you want I can get you the grind # you won't be sorry.
