Been collecting parts to put together a hemi for a long time. I had gotten a 4.5 hemi megablock yrs ago, picking up a piece here and there, I am pretty much ready to get it together. I was doing a 557, 4.375 stroke, then I got a deal on 4.5 eagle crank and 7.1 rods. Then I saw these for sale and grabbed them. They are 1.35 compression height with 74cc dome, so they should be like .020 from deck with 11.3 to 1...... I have new victor jr top end and stage V rocker assemblies, two 800 thunder series edelbrocks, the hyd roller the kit comes with, plus 2 other solid rollers to pick from. Also a new set of crane hyd roller lifters and a new set of comp solid 829-16. Have pans and oil systems, distributor, water pump, but still need gaskets, rings, bearings, chain, pushrods, valve covers, trottle linkage, and time to do it. Also have a new repro chrome dome with base for edelbrock carbs.
