New crank, rods, pistons, jessel belt, valves, locks, springs, valve job, new lifter bushings, rings, bearings, crank scraper, and oil pump guts. In my notes on the build at the end of 2021; " #5 intake has a pit in the lobe. " Apparently the heat treat on the surface has degraded further. The current cam has 1718 int and 1862 exh lobe on 112 lca, 4/7 swap. The cam in hand has 1719 int and 1864 exh on 111, std firing order. So .022' more int lift, 4 degrees more exh duration. Same lobe designs. The lifter wheel apears to be undamaged. I'll check but it had tons of piston to valve and some room left on coil bind as well. Doug Last edited by dvw; 04/20/24 07:44 PM.

The other issue is the screen windage tray is cracked, again. It has a very nice crank scraper. I'd like to leave the screen out. But make a baffel to shield the oil pick-up from the "line of sight" to the crank. Something like this. Doug Last edited by dvw; 04/21/24 07:47 AM.

The gaskets, yup been there, the windage screen, yup been there. Not with big blocks, because I will never used a screen in one, but my small blocks with race pans and screens back in the day, I had screens crack. That setup you have with the carboard covering the pickup will be fine I think. 67 Barracuda street/bracket car 11.27-119 68 Dart 502 BB 8.70s-152 414 cid SB Dragster 7.65-174

an8sec70cuda I Live Here Joined: Jan 2003 Posts: 13,363 Marion, South Carolina [><]	Doug...I had the same issue in 2021 w/ an Isky hydraulic roller. Was in a good friend's boat with a 440" sb chevy. The cam had been run roughly 5 summers, but not a ton of run time. I'd built it originally in 2016. It had 3 lobes that looked like yours when I took it apart. They also said bad heat treat.

Later sending me a conformation # and shipping the supplies at N/C. Great service. Ordered one pair of lifters from Isky as I wasn't sure I could send mine back for repair and get them by next weekend. Cleaned up the cam and installed it in a spare 440 block. Modified the degree wheel to bolt to the cam. Set up the dial indicator and mapped the cam out to make sure it was what the numbers on the cam said were correct. A little mind game figuring out the cam with no crank installed for TDC. Along with the fact that all the numbers were reduced by 2. I started by finding the int C/L and working backwards. It all looks good. The int lobe base circle is .030" smaller, exhaust .015" smaller. At the last build every spring was checked for coil bind. For some reason the springs with the greatest coil bind height are all on the intakes. So I'll move them around at the .024 extra lift gets it a little close. Tetsing next wednesday. Racing next weekend. Doug

Checked all the lifter wheel play with a slick homemade tool from Hardcore. Everything cleaned. Cam is in at 108 C/L, .050"-.060" to coil bind. Rocker ratio is little over 1.72. Lift came out to .837/.810 w/o lash on checking springs. Piston to valve .075 int, .110. Borrowed a very nice LSM on the motor spring tester. Found the #8 exhaust spring about 35 lbs low. I have spares so that'll get swapped. Today I'll get the windage screen fabbed up, install the pan and steering linkage, radiator, alternator, add oil, trans fluid, and coolant. Still waiting on the lifter. It can be installed thru the distributor hole. So if It takes to much longer the valley inspection cover, intake, and carbs will all get installed. Wesnesdays weather looks good. Going to try and test before next weekends first race. Doug

With a litle work using tig wire it can be installed with the valley tray and intake in place. Moved the trans breather. It's always been lower than the trans. Located just in front of the rear license plate. Never overflowed, but t didn't vent as well as it should. And just for Hardcore B instead of wasting time detailing the test block. The undercarriage got cleaned and waxed. Along with the engine. Doug

Track prep was great. Had the front shocks full tight to keep from 60 ft with the rear wheels. What a whirlwind 10 days. Doug Last edited by dvw; 05/01/24 11:15 PM.
