What would the ideal deck height be on a hi performance engine? I built a 2165 and my deck height is .043 I just added .010 barrel shims. any info would be great.

I like it as tight as I can get it. every engine I build gets less than .050, my engine runs at .032 and turns 6500RPM daily,

When the squash area between the piston & the head is small/thin the VW air cooled motor will produce more HP but will require a better grade of fuel for a given compression ratio. So If the gas is not the best its better for to have a wider or thicker squash area. And the compression ratio depends on the Fuel, Timing used. Vic.

Please give us the rest of your motor combination. Heads cc's, valve size, carbs, and camshaft. Also what kind of car and driving do you do. Tim

Engine goes in a street legal rail, I raced it once last summer got two runs then I blew 1st gear. I want to use this for a race/street motor.

I'd get some heads with some bigger valves, 40 35.5 or 42 37 with about 54 cc's and run the deck about .045. I haven't run the calcualator on that but is sounds about right. Tim
