Ya if you could measure yours also from center to center of the tips that would be great. Again, I would just like to find a happy medium so I don't limit myself to just the cmi's. I'll adjust the height according so I Just miss the steering components.

Thanks,

Cool, that should put me in the ball park. My width was the biggest concern considering the cmi's can vary so much. If you rotate the tails even slightly it can really throw off the overall width. Like I said I just wanted to be somewhere close in case I went with gils or stainless marine, etc.

Thanks again,
John

yeah, 590HP@6250 and 560TQ@5000. There is probably still some left on the table. I was only running Barry Grant/Holley 750's and they were pulling hard on the jets. I had to jet down instead of up. I would like to try some 850-950's.

I have 4" pipes going through ~5 1/4" wholes with the Stainless and rubber rings over them

awesome. try jims 950 hp. those are actually flow like 830 cfm. might be worth a try if he still has it. you might be surprised.
