the bearing clearances ended up at .00325 on main and .002" on rods using coated rod bearings. crank end play is .0055" and rod side clearance is .025"-.027". pistons look to be .010" in the hole. the 1mm rings went in the bores easier than i thought they would as they didn't want to stay in their grooves. used wd40 on rings and torco assembly lube on bottom of skirts. the cam is being reground by Bullet and will be 267/275@50 .688/.688 lift on 106 per kurt@Bullet. it is a solid roller. so as of now i'm just waiting on cam and heads and then i will continue. goal is to have it done and on dyno by christmas. should make between 650 and 680hp.

Thin rings are where it's at.
Remind me about the heads/intake.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

Sounds cool Dave.
Would have figured the cam would be more in the mid 270's@50 range.

indy heads 360-1 and indy intake ported. dwayne says heads now flow 20 more cfm at mid lift and should flow 330 range at .700 when he's done.

My 4 inch was 273-280, Dwayne specced it with mild lobes so I could drive it around some.
The new owner moved up to another Dwayne cam that was 276/284 with more aggressive lobes and the car really picked up. Same compression as your running.
Most stuff I have seen in the mid 260's works good on edelbrock combo's.

267 isnt too far from 273. i was told it takes 10* change too tell any difference. i told them it would see some street driving, but mostly track. too small is better than too big any day.
