Well its not for my blazer or a truck for that matter, but its still a pretty bad ass big block.. Heres where a lot of my time and money go besides into my k5: -'67 camaro RS/SS -454 .070 over, steel crank, forged rods, forged je pistons, Performer RPM rectangular port heads, decked to 98 cc's to achieve 11:1 compression, heads lightly ported and polished inside and out by myself. ARP head studs and fasteners throughout. -New CAM (I degreed in) and REV KIT: Crower custom grind SOLID ROLLER, 260 degrees duration @ .050, .590 lift, New valvesprings (212 in lbs. of seat pressure!) New pushrods, (lifters and pushrods weigh 44 grams less per set!!! Lightened up OVER 3/4 of a pound out of the valvtrain! ) -1.7 scorpion roller rockers, Dart single plane manifold, Holley 920 cfm carb, hooker super comp 2-1/8" primaries to 3" & 1 chambers. I also just put in a stock volume & pressure oil pump along with a windage tray, and a crank scraper to help control some oiling issues.. Oh yeah, rings gapped a little bigger for some juice and a sportsman fogger kit. It fired right up.. appearantly i know how to put together an engine and adjust a solid roller cam. Only problem is its weeping a little outta the head studs, hopefully it should go away after a few heat cycles. Should be making a little more power this time around.
