302 casting on a set of 318 heads

Thanks. I still got to pull the teener out of my 67 notch shell. I put it in there as a mockup for modding the wiring harness, as well as mocking up the FEAD and making custom alternator brackets for a denso mini alternator, and custom making a fiberglass fan shroud setup for the aluminum radiator.

When it cools off a bit out there, I i will get it out of the car and on the stand. Car this engine was from was an 88k mile 1974 granny moredoor dart. Am hoping the bores are decent enough to ball hone it, rering it, put new bearings and oil pump in it. Then add the cam, a Cloyes true roller timing chain. Got a new magnum 3.9 chain tensioner for it. Mildly ported 302s and an LD4B. Hoping for about 300HP w some low end grunt. Should be plenty with 3.73 gears to make it a fun street car.

Was looking at a thread Rainy has on a 74-75 teener she pulled the heads off of. Flat top pistons, and zero deck height. If the 74 teener I have is the same, those 302s could put it at a 9.5-1 ratio. I am thinking the 1.75" and 1.50" valve sizes are prob fine for a stock bore teener. Too big of a valve and too much hogged out of the runners and port velocity suffers with such a small bore.

The plus with the teener though is a 4.00" stroker crank will make it into a 390. And it fits easily.
