Thread: 305 stroker

Tweet

i am just nearing the firing up and break in on my 331" (stroked 305)....used 76 400 crank, rods are stock 350, a little beefier than the 305 rods same length. heavily ported 416 heads with 1.84" intake and 1.5" exhaust, both have been swirl polished, screw in studs and 1.5:1 comp roller tips, Custom Colt Cams 270 magnum
221@.050 .465" lift 108LSA......runnng an edelbrock oldschool torker and a 600 holley.......I have a pretty good idea it will have some decent power. When i run it i will post the results, this will see a chassis dyno after christmas.....im not sure on the numbers but if it made 320 at the rear wheels i'ld be very happy cause I only put in about 1600 cdn into it. Its not a bad motor, but the extreme porting and polishing i did on the heads are what will make the difference. I think the cam i chose is a good choice, I may switch to 1.6:1 rockers after check for clearance issues with the piston. Im stayed conservative with the lift in the begining due to the unknown piston to valve clearance but if it will work the 1.6:1 will bring the lift to .496". we'll see, .....hope this helps.....also if you are going to run a 671 you need to o-ring the block, and definately use 1.94: intake valve. you should be fine with your intentions but use beefier rods and a forged crank and also install splayed 4 bolt main caps. lots a psi on those small pistons. but i will work
