Hey guys .. ive been taking a long time to get my A into G on the race car once again, but slowly & surely its starting to come together. Ive now completed the cylinder head, its all back together, with new stainless valves, and everything is once again spotlessly clean.
Today we dummy assembled the engine - two pistons in the centre bores, valve clearances set, and a new Felpro head gasket. we strapped it all together, timed the engine up with plastigauge on the pistons to make sure we had adequate valve to piston clearance. The result ... not so much. Any amount on the Inlets, (0.080" +) but only 0.004" on the exhausts - needing somewhere between 0.056" and 0.076" more clearance (we are going to go with the latter of the two as this engine is going to be the "safe" option.
With any luck the exhaust valves in the pistons should be pocketed within the next few weeks - so not long now until the engine build is well underway. Will keep you posted !
Take care all.
