looking for cam and pistion ideas.

(Quote: RustyRatRod – JE pistons? Seriously? The hell you say. Do your budget a favor and put the Speed Pro forged six pack piston in it and be done with it.)

Great statement by MOPER we always just assume we are running engines at sea level, but I know you will lose ½ to 1 full sec. in Denver so I think that is a great point. As for pistons and rods yes there are /and have been lots of cars racing with six pack rods and pistons but there has been many who have come apart too. RustRatRod makes a good point, it all comes down to what you are doing in those hole, Nitrous, high compression and so on. Chambers: open, closed, heart shape, and valve size. Here is the draw back with the 6-6 idea the last stock ones were made 45 years ago and most people who ran them ran them hard or they wouldn’t be apart and for sale. The stock 6-P Pistons: you would have to change the pins and locks, they takes wide rings both Speed Pro and stock and they are both heavy, real heavy, and with the stock ones you have to have a block with a very straight STD bore. The Speed Pro forged six pack piston is a good piston (Depending on the head chamber) but it’s not a true forged piston, it uses a lot of Silcom, but they do have a good price. At a minimum with stock 6-P rods they would have to be magnafluxed, polish beams (to stop cracking), check and maybe replace the bushings, and change the rod bolts about $150 to $300 worth of work. Or just buy a set of I-Beam eagle rods for $250 or H-Beams for $450 to $600. If it is a mechanical motor (NOS less than 100hp) then I beams: Eagle, Mopar LY, Good Six pack rods will be fine and almost any piston will be OK: Stock, Speed Pro, KB, JE, Ross, Seal Power just watch the weight. If there is NOS involved there are two routes to take with rods and pistons. Pistons - as little silicone as posable in the Piston is the rule, 150hp NOS or more forged pistons are recommended. Rods: 150hp NOS or more you have two paths to take. Strong or absorbing, what I mean is H-Beam (Strong and heavy) Aluminum (Absorbing and light), it’s all up to you and your budget.
