Ok this is all I know so far. I am waiting for info. I am sure thoes vans didn't have V8's. Being an 86 it can't be a WCT5, can it?
This guy drives all over the country every weekend pulling a trailer full of race gear and car. With a V6 T5 and a stroked V8.
[What do you mean stroked, Buick engines come stroked factory.]
I ran a thread a long while back and it was allways 50/50
some blew a T5 with just a stock 305, some had stroked out motors and never had a problem.
Very interesting though none the less.
"So...there I was, peacefully traveling eastbpound on I70, in beautiful western Colorado, going to a roadrace in Pueblo two weeks ago, not suspecting nothin', when a giant teaffic hazard, traveling ion the slow lane well under the speed limit loomed up.
See, it's like this, I was doing 75 or so in my 1986 GMC Safari van, the one with the all aluminum Rover/Buick 309 cu/in hybrid engine and T5,"

"T5 is WC, fitted for van/pickup use, V8 guts and cable speedo (some were set up like this). mAdded info, I use 30 wgt motor oil in the T5. NO reason at all to run ATF, it doesn't lube, is designed for hydraulic systems and is only in those transmissions to "reduce drag for fuel mileage". Actually, ATF just causes premature wear in standard transmissions.
11 inch clutch, hydraulic actuation. Special Trans-Dapt large clutch bellhousing (a friend of mine is the new products manager at Trans-Dapt).
Block, 4.6 Rover crossbolt, mains bored for Rover single round rear seal, cut to fit 1964/1967 300 Buick bearings, bored from 3.700 to 3.737, T type sleeves installed
Crank, Leyland P76 Australian, 3.50 inch stroke, mains cut down to fit 300 bearings. Rods left alone, .010 under.
Rods, Scat H beam small journal Chevy, narrowed to clear the Leyland journals.
Pistons, Silv-O-Lite cast, 305 Chevy stock, slight dish, 10.00:1 c/r, stock pins/rings, set up for full floater pins.
Early V6 type dual roller timing chain, sprockets.
Crower cam/lifters
Modified front cover, homemade oil pump, tock volume, new design, no cover wear.
Heads, 1964 Buick 300, late large Corvair valves, Crower springs/keepers/retainers. Stock Buick 215/300 rockers, Smith Brothers adjustable pushrods. Chambers are welded up and cut into heart shape, like Doug Roe and I used to do for stock Vega 4 cylinder heads when
Doug had Priminion in Phoenix years ago, piston tops match head shapes.
Intake manifold, later Rover 3 piece plenum, EFI, Mustang 21 psi nozzles, dual 2.100 inch throttle body from Z28.
Headers/exhaust, Homemade headers, tri-Y, X pipe, dual quiet mufflers.
That's about it, 307 cu/in, weights are in the 365 lb range for the engine, 75 lbs for the trans, 100 lbs for the bellhousing and clutch.
Climbs hills with TWO vintage Kawasaki H2R racebikes in the back, as if it were empty. 31 mpg at 70 mph, 30.5 at 75. Uses reg or mid grade gas.
I use the same 30 wgt oil in the engine that I use for the transmission, CarQuest natural oil, NEVER synthetics of any kind.
That's about it, another one is almost ready to replace the 215 and T5 in my 1972 Vega too."

interesting. I've heard the stroker formula before but never heard of anyone building a tow rig with one.
Personally I'd like to stroke one and drop it in a british sports car of some sort with a '730 ecm replacing the lucas junk.

The owner is Dave Ray AKA IgnitionMan over at BuickThunder
And he is the man. He designed most of the system you find in older GM cars. Still builds for many race teams and sells custom built small bodie HEI. Large in cap ones are junk by his spec's but can be fixed. He is super picky on coils. Only a very few pass his RPM test.
