You should do dome reading on camshaft theory and you’ll also need to rerun your dynamic compression numbers with that cam.

I personally think a single pattern cam is horrible choice for a SBF...

I don’t know about the head bolts.

Seriously do some checking on the cams and go read http://www.fordification.com/forum/view ... =3&t=87861

Ford heads are generally not very good on the exhaust side, so you’ll find a lot of people (me included) like to run more exhaust duration and lift. That 268H is a single pattern cam and a very old design at that. I would go with the Thumpr all day every day out of those 2.

Has anyone done a DIY project on the radiator mounting kits? $40 plus shipping for a few pieces of rubber and bolts seems high.

That is a Radiator SUPPORT mounting kit. It is basically the front set of body mounts.

I need to come up with a DIY for this. $60 for this is a bit much.

Block and crank are at the machine shop. As soon as I get word from them I am ordering the Federal Mogul kit. I found a bent exhaust valve and one exhaust valve was sticking open. I am sure that was and issue with loss of power. Inside the valve guide had a bunch of sticky oil in it. Cleaned it so its smooth now.

I want to replace pushrods, I have a 302 with 351 heads. DO I buy rods for a 302 or a 351?

If you're using a 302 block, you'll need 302 pushrods, but if any mill work has been done to the heads, you'll need to measure them to get the correct size or your pistons might rudely introduce themselves to your valves.

As long as the base circle is the same and the lift is within the tolerance of those old cast rockers stock length will work.

SO upon finding out my head bolts are 7/16" BUT I have 351 heads that use 1/2". I noticed that in order to run 351 heads there are step washers that are required. I did not have step washers on my set up. I don't know if this was done from the factory or not. what should I do now?
