You can probably run it in K and would be 4,200 lbs with driver, the heavier classes L and M will break more parts.

Ya can always start a New One!

Your HP factor is 310 as I recall.

You do not use Factory HP.

The 360 will be a much easier build and bang for the buck in that car. Plus the rating is more favorable.

360 @ 270 HP!
Paul is right as he usually is on this stuff.

If you like the 400 = put it in a 73 Mopar B body
400 with Aluminum Heads @ 296 HP
and you have a very competitive 1.2 under combo!

Ask me how I know?

John for some reason I have been under the impression that the Edelbrock aluminum head replacements for Mopars were "unobtainium".

Is that not the case?

Thanks,
Bill

Not if you bought them before Edelbrock got sold out!!

Remember you are talking to a guy that owns over 200 sets of
Mopar heads.
