Solid flat tappet.
It has 30wt. Brad penn in it right now for break in. We started it and broke it in on the outer springs.
It's too damn salty on the roads to drive it now, so only 1/2 hour "break in" so far.

I'm still nervous about the cam going flat, but we did everything we could to mitigate it.

The Crower falt tappets with the oiling hole seem to be the only tappets worth anything. I wont run a flat tappet anymore with the all the tappet horror stories I've heard and seen myself.

I've been running these and so far so good after 40 hours last season; http://johncalliesinc.com/product.php?ProductNo=5045

I was actually joking, but my brother has 4 seasons on his Crower oval track solid flat tappet in a 383 stroker. He used the EDM lifters, seems to be working fine in his Glastron. With today's oil I think the ZDDP additive is a must.

Don't bet on it. You'll probably lose a few hundred rpm with that carb.

Why would that be?

Cause his $900 upgrade that is suppose to make 20 more horsepower than anything else actually makes 30hp less than an out of the box Holley.

Cool! I bet it's fine. It's just the first start-up jitters!!! I've heard of guys painting white marks on the push rods and firing the engine up without the valve covers to make sure they were spinning!

Would love to see some pics of the car!
