The mild cam also won't really let you increase compression over the stock 1.7 levels of over 8:1 without starting to run the risk of detonation. (I forget the stock figure now, it may have been 8.6:1 or 8.2:1?) You might even think about dropping it a bit to five the larger bore cylinders a bit more time for a complete burn.

That said, the bottom end of the motor will work fine for a 1911. No changes are required other than pistons and cylinders.

Thanks for the response. (Ignore my PM)

Iím moderately familiar with carbs, done a bunch of Harley, while single and small. I can tune it. Duals will be a new experience.

Iím familiar with the LN heads. Nice but out of the budget.

Back to the cam quickly: forgive my confusion, would it be beneficial with this set up to throw in an 86 grind cam? Limiting the motor not doing it? D. Elgin, scat, Eagle, etc.

This is a budget build, but not El Cheapo. I have no problem running a mild cam if it will make a day and... evening difference.
With hopes it will not grenade.

Thanks Dave!
