Magnum 360 heads "best" for my build?

octanejunkie said

I am leaning heavily towards this cam, a few questions:
What carb and intake are you running?
What rocker ratio/valve springs too?
What is your static compression ratio?
What trans are you running?
What is your rear gear ratio?

Would love to know so I can tailor my build, thanks!

I currently have a Holley 670 on the car but the 370HP based off a 102 mph trap speed was with a 600 Holley. The car is stronger with the 670 but I do not have any times.

The intake is a Professional Products CrossWind open plenum dual plane (similar to the Edelbrock AirGap).

I am using stock 1.6 ratio magnum rockers with Mopar Performance springs (the R/T which is good for .525 lift).

The static compression ratio is a measured 10.6:1 and the cranking pressure is 185-195 psi.

The tranny is an A833OD 4spd.

The rear end ratio is 3.55 with 27" tall tires (255/60-15).

When I had it to the track I was running smaller tires (235/60-14) and the leaf springs were tapped out and I had real bad wheel hop when I launched it hard. So, my best time was a very traction limited 13.7 @ 102 mph with a miserable 2.2 sec 60'. With better tires and new springs the car should easily run low 13's maybe even a high 12.

My car is a nice weather daily driver. I put about 7500 miles a year on it between April 1 and the first time they slat the roads in Nov/Dec. Since I drive this car a lot mileage is important to me and my set up gets 16.5-18 mpg around town and 21-22 mpg on the hiway. The car also runs on 89 octane and I have used 87 in a pinch, I just have to be careful below 3000 rpm or it pings.
