244/248... you better have great flowing exhaust runners. That split is to close in my opinion.
worked well in mine with 2” cmi. Non ported. JME |

Switched out a straight split cam with one that has a 6° split and it was much healthier and better performing. These heads were optimized and have great exhaust ports. JMO |

No but I like it. Very similar to mine with a little less lift but not much… like .013 less + -
This would be a little easier on VT 623 hp at 6k on my 496’s - same duration! https://www.flotekheads.com/store/Bi...2cc-p130160438 |

Another note: if you are truly at 10.3:1, the cam you have is too short in duration. The cam you have was trying to achieve more cylinder pressure , which you don’t need nor want now. Note#2: You where reving 5500rpm. My guess is that was just passed max power. 224 is a tow truck cam for near 500cid. Somewhere 236-240 at .050” intake duration is where your motor will want to eat. Prob 240 :) You have an exhaust to handle it? |

Reversion. You have to have long risers or dry exhaust.
I always thought the key to mitigating reversion was lob-sep of 112 or more. No? Thanks. Brad. (937)545-8991 |

(937)545-8991 -Tightening lobe centers (lsa) does also. -Amt of Exhaust open degrees past TDC on intake stroke is what really means the most when it comes to reversion possibilities since the exhaust valve still open (but closing) when piston going down drawing in air from both valves (intake valve starts opening before tdc intake stroke) at lower rpms. Look for some of my cam charts comparing the mag 454/502MPI/ HP500/Crane 731/500EFI/525EFI/Crane 741 and you’ll see seat overlap, .050” overlap (including btdc and atdc), etc, etc. Really good info that if studied, paints great pictures. :thumbs |

I talked to RMbuilder a few days ago. He seemed to think I could get 620HP out of my engine. I would need AFR heads, new cam and bump up comp.
