Tom, I started in '58 with a Clinton A400, tried dual E-65's, a prototype AH58, then got an Mc5 YECCCH. Mr. Mac sent my Pop a pre-production Mc6 conversion, and I was off. I ran the '6, switched to an Mc20, back to a stroked Mc10, modified per Gil Horstman's instructions to Pop, tried a '30 and a '40, all modified Horstman style. Went back to the stroked '10. It was the best 6 inch Mac. I ran open square-port 101's in B Limited in the late seventies before switching to open LMR's and open Atlas reed motors. It wasn't until vintage that I switched to the 610's, and got lucky and started right out with Bonbright modified engines. They're fast and bulletproof. I like the beefy block, and I like the 1/4" bolts. I love Macs, I just don't like rebuilding them! Ted
