Default CMI E-Tops for 272 sr-1 Formula

Has anyone installed a set of CMI E-Top's in a 88'-90' 272 sr-1 Formula?

I posted in the Formula section with no reply and need advice.

Mtgbiker, it doesn't look like the 272SR1 owners did a Lot of mods to these. I have one that I have did quite a bit to but no help to you on the exhaust, this is one of my present limitations. I am running the standard Stainless Marine manifolds with Whippled 454s. I think Mopar used IMCOs or Gills on his if I am not mistaken.

Ok,,I'll step in,,a few years back I had an 88 272sr1 with twin 454s,,,when I put the new motors in the center to center specs( I think it was 33") wasn't spaced far enough apart to use the Lightnings or the CMI's, I ended up moving the engine hatch ram and using Bassett headers.
Hope this helps.

Going to be pricey, but I believe CMI and Trick will build a set for my rig. I just need to double check the center to center measurements as noted.

I went through this on my 311 years ago. If you have a silent thunder platform on you Formula, you might have a problem with reversion. The thru-hulls are mounted higher than standard, causing the tailpipes to be almost horizontal. 3" rise CMI's would not work on my 311 wtihout cutting a lot of structural fiberglass.

For enough money you can get anything built,,,at that point in my life the budget was alot slimmer than it is today..had to use what was available across the counter..
