do you have a copy of the cam card by chance. Personally I'd use it and not look back. How I got away with cams used years ago without reversion is beyond me. One bad choice but was during the marine learning builds nearly 30 yrs ago and cam was on a 108.

You can always swap out to dry pipes and cheer some blow boaters up. Hah. You'll be fine. Is that a custom grind or Howard's by chance? Specs don't sound familiar. Just curious.....

A 265 head, 228/234 cam for a 540? Holy $hit.
You guys are nuts, but I guess if it just laying around why not right.(sarcasm) While you`re at it maybe you have a carb laying around ,maybe from like an old lawnmower or something. It`ll be perfect for this build.

The heads are 088 with slight port and bowl work, 10.5:1
Cam specs are 631 both sides and duration is 252 on both sides as well on a 113

Thats nice power with the 088, i may be looking close to that i have a bit less compression the cam will be smaller but the afr 265 flow way better than a stock 088 especially on exhaust side and low lift areas but yours are cleaned up some thanks alotfor the help

$337.00 for a Comp is typically a cast iron core. Be careful and always question and then follow up and make sure their answers are correct.

Those 265's will fall off early IMO. Id expect to see 5200-5300 unless you let it breath better. If that's the head you must use, match the parts. Trying to over cam a smaller head will disappoint you.
