Exhaust runner

Intakes...

Intake bowl with 2.08" valve 'dropped inside'.

Should keep those nasty big blocks at bay.

I mulled this move over for a long time. Originally I wanted the W5's. Not as 'aggressive', but much easier overall, on the pocket book. The W7 and up, have different valve angles, they oil through the pushrods, and they work much easier with the 48 degree lifters. So, custom pistons, oil mods and an R3 block is almost a must. The biggest decision was the 'street factor'. Ultimately, I want this motor on the street as well as the track, and work well in both forms. I think of it as a de-tuned hemi small block.

The valves are 2.15"X1.60". The intake runner is 252cc and flow somewhere around 350CFM.

That looks much better.
