I finally got around to using my gap gauge to determine the recess on my Windsor pistons. They're .018 (.457mm), with minor valve reliefs on top left and lower right of the oval recess. With my 70 heads (60.4cc), what else would be needed to assess the compression? No idea why the opposite side valve reliefs. The deck height is for a 79 block, which I read was higher than earlier blocks - don't have that number.
The cam is an Edelbrock performer plus, with specs 201/214 duration at .050" lift, with lift 448/472.
Just trying to figure out if I should keep the short block as is, or replace the pistons and cam/lifters/springs. I'm going to keep the heads, and spend my 3-400 on roller rockers/studs/guide plates, machining a bit for the studs, and maybe pistons.
Read at Edelbrock's site the following: CAUTION: Use Edelbrock Performer-Plus Timing Chain and Gear Set #7811 or #7820. Do not use late model timing chain and gear sets that are designed for emission-controlled engines. These timing sets are machined in a retarded position and are not recommended for this camshaft installation. Edelbrock Timing Sets feature three keyways for specified timing selection.
Guess I better figure out if that's an issue as well. I'll be taking off the balancer and timing chain cover today to figure out if the cam is properly degreed. Fun, fun, fun. Eric.
