H23 Delta 272 camshaft issues

ill be sure to do that. thanks for the tip

Yeah over revving did it!!! Espcially that high. I'm guilty of the same thing, ain't no shame.

[dbsharp]

um, since it has been to the machine shop it has only seen 250 rpm's.

My head is fine. Some how carbon built up on the back of quite a few valves, and once they were cleaned they sealed right up!! As soon as taxes get here Ill get some springs and have some numbers from the 272.
ps. We vacuum tested the head and it is good. I think that once I get my cams in, I'm going to take make a thread all about my car and set up, and then some dyno numbers!

got it running again today. thank god. just waiting on tax $$ now.

I will be ordering springs on Friday. I'm considering going with the crower springs because they are tested production springs. When I spoke to bisimoto on the phone it seemed to me that maybe he hasn't spent much time into r&d on the h23, he needed me to measure id, od, and install hight, which is not a big deal, but I would think that he would have a h23 head laying around if he did much with them. I trust that his springs would be of the best quality, but I have been reconsidering putting a untested valve train part into my daily driver.

woho! Just ordered some valve springs. I would have to run over a 600 lift to get anywhere near coil bind on these springs, so they should be good for any cam I may want.

Good deal, happy for ya. Besides, with the Crower valvetrain, you and always upgrade later to nastier camshafts and not have to remove the head, since valvetrain will be ready for them cams.

my current thinking is this, for now a 272 cam, and very possibly a quality header, then I will put money toward all the other things I want to do to my car, like suspension and repaint it etc.... then build the f22b head and a f22a block to be pretty nasty na, and set up a hefty shot of nos for the strip. this will be way off in the future though.
without rasing the compression, I dont think I want a cam that is much nastier, my dynamic compression ratio is already at 7.5 and that is about as low as I want.
