Hodup now. Let's try something like that in yours first. Should idle very nicely for you. Besides you'll never guess what I'm going with??? Might surprise you. actually kinda close to something you mentioned in a thread a few weeks ago.

On a serious note I have a question for you BB. I realize stroke eats up duration but let's say for same stroke engine how much would .100 larger bore size difference make with same duration cam in regards to peak hp rpm? My gues would be minimal but what's your take on that? Maybe 100 rpm or slightly more? Just wondering.

I have a nice combo for 598. If you have any questions send me a PM and I'll share specs.
Also, with a bravo and that much cubes I would let it spin some RPM to help it live. 5400 is going to kill it quickly IMHO and I think 5800-6000K is more where it should be.

Thanks for all of the advise. My builder called today. Thought I should either change heads from the BB-2X of do some work on them as they are stock. I'm having them go ahead and work my existing heads, new valves, springs etc. the are boring it to 4.61". Thats all I got today.

I am running Jessel shaft rockers ( stock ratio)
I am running AFR 357 CNC'd heads.
8.6 to 1 ratio JE pistons ( plan on adding a M4 Procharger eventually.
Crower crank, Lunati rods, Big M block, Edelbrock sequential port EFI intake with the Holley 2000 CFM - Hp system.
Idles smooth and has so much torque it is unreal. Accelerates like it's tail got stepped on.
