I am soo happy, Mike did a great job, don't you think? Now thats porting, and the plennum and gaskets are port matched as well.

Mike Graycar did it, as well as the plennum and base. He had finished stuff on ebay and I realized that he only was about 70 minutes from me so I just drove out and dropped them off, great work and a really cool guy.

Looks good. but after doing mine, I think porting the divider on the 5/7 cylinders is a bad idea.

With similarly ported SLP runners, my 88's HP peaked at 4800rpm, with headers, stock 113s, and the stock camshaft.

I think it's an effective mod. Good luck, and post your results when you have them.

If you were to use a piece of 3/8" hose or equivalent (insert in runner,
mark, remove and measure) how long are the divided portions of the
runners, now?

Have the diameters changed appreciably?

about 5 inches, the dia is close to original, mostly just removed casting irregularities.
You have to see the plennum, I didn't get pics of that yet, but I will post them when I do, real artwork.
