Luke,

You should use a blowproof bellhousing, lakewood, etc. because of where the flywheel sits relative to the footboxes - a blown clutch or flywheel can be a disaster.

The belhousing may need to be trimmed on the bottom to fit the frame - if you haven't gotten a manual from Peter yet you should probably do that before gathering up parts - it has a lot of detailed parts information in it - including some parts modification info. Also, there is also a spacer required for the Tremec.

The 3550 is rated at 350 ft-lbs, the TKO is 425 ft-lbs. If you're using very sticky tires you might consider the TKO, but either should be plenty strong enough. I'm using the TKO, for my 320 HP 302, and a Lakewood - insurance in case I upgrade the motor at some point. A 3:54 rear is a nice match for a TKO.

Fifth gear is a very big jump (.68:1) on the 3550 and TKO - hard to pull at high speeds with a small block - but great for cruising (~1800 at highway speeds). The 3550-II and the TKO-II both have a .82:1 fifth as an alternative.

Best of Luck,
Jim
