Where can I find and buy one of those Tommie Smith bus engines?

I have heard those engines are WAAAAYYYYY overrated.

And so it has begun

Super excited about this... Here is the list of parts (so far) for the Double Cab engine build:

2110cc
Aluminum bubble top case
CB 82mm crank
AA 90.5 pistons
Unitec I-beam Rods
Stock heads
CB cheater cam (2280) Adv. 274 Dur. 222 Lift 359
CB Big foot lifters
Swivel Feet Rockers
Weber 40 IDFs
CB Dual Carburetor hex linkage
Empi Welded/balanced fan
Empi Alternator Kit
Empi Oil Breather Kit
Gene Berg External Oil Filter
Scat 36hp doghouse shroud kit (Will be powder coated white, figured that would look nice in a rusty white Double Cab)
Lightened flywheel
Bottom end dynamically balanced by Lyle Cherry

Trying to decide on exhaust.

Really glad I met Tommie :thumbs:

Make sure you test fit and trim all your tin before sending to powder coating, especially the fan shroud. The raised roof cases necessitate quite a bit of trimming of the shroud.
You don't need big foot lifters either, save money and weight and get standard ones.
Stock heads will severely limit your engine, consider some mildly ported 40x35.5's.

Yep.. Already told him .. we have to dry fit to the long block all the tin.. before sending to the powder coater..

as for the big foot.. lifters they are priced the same as regular ones..

the stock heads have a mild port clean up on them.. in a bus they may only limit so much.. with the cheater cam and 40IDF's on a stroker motor they make for some great bottom end torque.. and in AUSTIN the hill country.. it is pretty awesome to have clean bottom end power.. at this point the lightened flywheel is the only thing I really didn't like .. around here on clean running heavy VW's the stock weighted flywheel is what I like.. but the rotating assembly has already been balanced.. so we'll leave it be..

No point in adding extra valve terrain weight, all it gets you is less power... I have .418" lift at the cam and 310 duration and I'm runing stock diameter lifters. The less weight you have to push around the better.

I would still go with a pair of 40x35.5's with mild porting, with stock size valve you are wasting the big crank and pistons. Remember the stock heads were actually designed to act as rev-limiters. You may have some torque down really low with those tiny heads, but with a properly sized head you would have that much (if not more) torque down low *and* way further out in the rev range. Soem extra revs come in handy if you need to pass someone. Throw an kf8 in it while you're at it. Maybe a -7 if you want to be more conservative.
