Bluedog Velasco crank # 5628623110 Henry is the owner, downey Cal. price for a 4.25 crank with chevy rod 2.20 was 2400.00$ I will find you L.A.Enterpize #
need4spd G-Force 7178674352# Mike is incharge fax 7178673983# competitionproducts have the same location./ Are you using BBC rods in your motor? these rods are 4340 steel with arp 2000 bolts I was told that the rods are good for 1khp. The steel is US not china. He said if it broke they would replace it no question if the rod was defective. There is an article in chevy mag about rods and this company explains what they do to there rods with maken the grain of the metal flow in 1 direction, they are shotpeen and xrays for any inperfections. Give them a call. 18002330199 Howard cams is 9202335228 They sell the same rods for the same price with the same manufactoring done. I believe that the rods are built in house. Ask questions I do, more than once. These 600rr trans are in vipers. As long as you are not doing 4G hole shots with this trans you should have no problem, Vipers use Pilots on them I think. I would n't put a softer tire on it and do holeshots or burnouts 200 ft long. Call G-Force and ask what the HP and TORK rate is for there updated kit. A new shaft and gear set comes in the kit. You can break thing part in your car if you bang it hard enought. With the motor you are looking to build I would not go with3.73 with a big block, 307 or 327 would be the most. You want to be able to cruise with the car also. I wouldnot call 3.73 a cruising gear. Hope this helps, build a tork motor with a max 6500 rpm and not worry about a hp. I think you will be happier when it is all said and done. Tork gets it moving, hp keeps it moving.
Good Luck Rick Lake
