it can only grind it so much,depends how deep the hardening went.

Maybe have Bullet design the cam and valve train to fit the application, and maybe the engine will run better and live longer.

Its a Billet Core , I would send it to them and see what they can do with it , the damage doesnt look to severe.

Yep without EXTENSIVE portwork they don't flow enough to support more then 650 or so at best

See a few things there, plus that amount of sealer around ports no good,

You can work merlin heads to make some decent numbers if your guy knows what to do, nice HR cam and rid that tray...

I have 572's with 9.5:1 Merlin 320's fully worked, with a 260/[email protected] and .575/.575 lift cam on a 112, Dart ported and matched intakes and 1050 Doms, dyno sheet show 765HP@5800, if you have unported heads and tons of lift you are wasting that "time" keeping valve in that range thats why my cams are low lift... spends more time .400-.500 range where head flows air. kind of hard to explain..

new cams, proper setup will run great! get rid of that pan,

Thanks! That pan is flash gordon. What cam, lifters and springs are you using.
to add insult to injury i found this when pulling the other cam out. Explains why there was no front to back

play in the cam

I am going to assume this is a 4.5" stroke 572? a 4.5 stroke engine will need substantially more duration to hit 5500, than a 4.25 or 4.00 stroke.

Ok , heres the deal with your current cam. Its a 108 LSA. I am going to guess, your intake valve closes around 49* or so, assuming your ICL is around 103 or 104. If you switched to a 114 LSA cam, with a 110 ICL , same duration and lift, your intake valve would close say 7* later, around 56*. This change alone, would extend the peak power roughly 300RPM or so, due to the later closing intake valve.

Your power peaking at 5400, is about right to my math on that setup. I would recommend going with a comp cams HUC lobe if you plan on going to a hyd roller setup. Something in the 254/264 110-112 LSA range, .680 lift. You'll make peak power a few hundred RPM higher, and have a little flatter power curve.

.050 duration numbers don't always tell the whole story.

ohhhhhhhhhhhh,,,
you using cam button or ???

yes has cam button. Pretty sure this ones on me. forgot to grind the water pump rear cover bolts down. See when i head back to the lake this weekend.

if u are running solid rollers , like i am,, u must sure to check gap or fore to aft play in cam button to timing cover.
it took me some time , but finally got what i think was 010 to 015 gap.

yea , used 3-4 water pump gaskets,,,also had to grind down bolts on backside of pump.
i had to do this stuff , as it was a new setup for me.

what did u do with cam bearing???
