MA-6 Option Corvette Dual Disc Clutch Rebuilders
Tremec doesn't offer a coarse spine TKX so the ultra-rare factory 10 spline dual-disc clutch needs them swapped for fine. The assembly is rivetted together and may have unique discs. Anyone know a good shop in Eastern Canada that could handle the job?

Re: Help with sbc 440 cu in dirt track motor. What cylinder heads
With a restrictive carb a big engine usually doesn't make if any more power than a smaller one, but generally has more torque.

Re: Polishing side beams
Speaking just to the processes: polish first then peen; the latter produces a compressed surface that resists fatigue cracks.

Re: Carburetor spacers
Square bore carb spacers, specific to single-plane manifolds: Four-hole, and open. What are the benefits/drawbacks of each? You did not mention "cloverleaf" spacers or "tapered 4 hole" or 2 plane "equalizers" or thicknesses ... one or more will usually pick-up but, dif...

Re: Lowering exh rocker ratio.
The preceding post applies, but only if the loss is confined to near/at/over peak power.

Re: MIG WELDING CAST IRON OLDS HEADS WITH CROWN 44-30 WIRE
How about forming steel tongues to match the edge contour of each port pair and welding them to the header flanges?

Re: Spark Plug Gap
... The posted required firing voltages are based on pure air, not fuel vapor or relative humidity factors. Seems like every engine should have an on-board recording scope. :) In talking to operators of bi-fuel (propane/CNG-gasoline) fleets, they reported that worn spark plugs would misfire thousan...

Re: Vacuum rule carb sizing
All else equal, carb size has no effect on idle vacuum. What does and is frequently overlooked is idle spark advance. Running say a 15°vacuum advance system could add up to 5" Hg., even with a locked-out advance curve, thereby widening the window of possible camshaft parameters.
