Tod i used what i had which is a set of BB2X 2.30/1.88 with a Ton of extra work including a matched 454r-intake with Tons of Plentum work which includes shortenting up the two front runners.
Par said i could have picked up another 50hp or so if i had went wih the Oval port head. but i couldn't really justify spending all the at extra Money for 50 and some change HP.
But if i would have had to buy a set of heads..i would have went with the oval port heads with a Sniper intake
I didn't realize this because never checked them but the chambers on those bb2x of mine were 128cc's ( large). which had my compression lower than what i thought on my 511ci..
Par had to cut my heads to get the 15.1 compression we were looking for..they are now 117cc....of course this caused for the intake to be cut to bolt up properly
also went with a 4/7 swap.
we gonna see how she runs in the next few weeks...i ran 5.96/5.98 et's at 115 mph with the 511ci ( motor)...i hope this 565 put me in the low 70 range without having to push it real hard. :roll:
