Mopar Small Blocks

nolongerracing · 11-12-2015, 10:41 AM

What are the Mopar 340 or 360 Stock racers using for blocks? Would like using a R block but am totally confused looking at Mopar Performance website. I know there are none on the approved list, but getting one approved is not an issue.

I think most racers are using either the R block or the new P numbered blocks. That is if they have any. Several versions. Most like the small journal (318/340) in any of them. So many people in the whole mess have the Honda journal stuff anyway. Original dated blocks are probably worth more to the restorers than racers. Just for a footnote, if budget or availability prevent it, I would use a magnum block. The metal is better, and the bores are in the middle of the metal casting and are usually available in the junk yard. They will oil through the shaft or through the pushrod.

R Block in SS, good luck finding one though.

Last time I talked to Kent Ritter he was in the process or getting his blocks approved for NHRA. Contact him at kent.e.ritter@power.alstom.com or PM me and I will give you his cell number.

I think there may be issues trying to use his block in Stock. Roller cam bearings, non LA oiling, oil gauge port (stock manifold will cover this up).

Using factory blocks, it is all I have.

R-block is the most popular but NOT currently available. I agree on the magnum platform or go old school and Block fill a oe block OR the new Ritter blocks are approved but the are Beefy and VERY heavy! I have a picture of one and I will see if I can get it to post here.

I was once told by a very good tech man the following:

"Just because it doesn't say you can't, doesn't mean you can."

The rule book does not say that you can change the cam bearing dimensions in Stock.
Super Stock says "any camshaft".
