Hello M&M,
I will be putting on a Holley 750 on my 351W.
It's got vacume secondaies at the moment. I drive the car on the steet only about 1500 miles a year. I will take it to the strip a couple times a year.
What components will get be in the ball park?

Engine components:
351W 30 over
10.8:1
Cam 246/[email protected] from "Money Maker"
Roush 200 heads
Hooker Super comp headers on the way
Victor Jr. intake
4.30 gears 28inch tall tire 13 wide
C6 2500 stall

Thanks,
Jason

That's an awfully big cam... You're going to find yourself searching for a looser converter.

While you are at it, a switch to a C4 will automatically (pun intended) pick it up a couple tenths.

Good Luck!

MY GOD MAGNUM! is this your street car? if it solid on the bottom it will make a lot of power upstairs. the carb thing is way too broad of a question, i think the 750 might be a little small but should be great on the street. bigger converter, c-4 trans. probably needs a smaller number pv, bigger squirters and quicker secondary spring.....but theres really no way to tell without being there to tune it myself and track test it for fine tunning.

Is the cam really too big for the street? I figure I coould get away with it if i ran a 4.56 gear??I dont wont to run a bigger stall because its mostly driven on the street and that gets to be a pain. What size cam should i go with?

Thanks!

My opinion, the cam isnt too big for the street if you had a convertor that was around 1000 rpm looser (at least). The whole streetability issue starts to go out the window when you start talking about 4.30 or 4.56 gears. If you are go to go that far with it, a looser convertor will make as much, if not more, of an improvement than the gears alone.

Just my .02, but I think that cam will be alright as long as the rest of the motor's done to accomodate it on the street. I ran a 255/260 solid on the street with no problems. My buddy runs a .620 roller on the street with around 260 @.050 on pump gas with no problems (it's supposed to be in this June's Hot Rod! white '67 camaro)

As for the carb, I ran a 750 model 3310 on my 351W (the type with the secondary metering plates and no jets). I removed the choke plate, I think I ran around a 77 jet up front, #34 shooter with the accel pump spring shimmed up, and the lightest spring avail for the secondary. This carb was good for low 11's NA with C9 heads.
