[A softball question for the Ninja and/or others]
This is the cam card that came with my 2357 engine, which was originally built by Rimco/Fat (long block) a few years ago. Can someone explain why with an intake/exhaust of 448, the lift was only set to 327 degrees? I'm about to rebuild my motor and a lot of focus will be directed at piston "deck clearance" and the valve train geometry that wasn't set correctly. Thanks. |

That RAT engine used those same KBs and a big cam.
There might be room! I would call Automotive Machine next week and find out what their "lead" time is. Clay Perrine said they have lost some of their fixtures and couldn't do some of the machine work. (like line boring!). I'd ask if they still did what you need. Sometimes they are backlogged for months... I've caught mistakes SOME OF THE TIME as well. Another member said he was going to send his work directly to LN. This sounds like the "preferrable" route IMO. I'd check with them regarding lead time as well. I never spoke with Eric about the T4 stuff. Deciding to go SWAPO reduced my dependance on machine shops... AM is not cheap either! If I had to choose AM or LN I'd go LN most likely. Eric, he has the 82 crank and all the stuff to make it work now. His case is the weak version, and the case may be warped. Fred, I DO have a stupid nice 73 2.0l case. I WAS planning on keeping it "just in case" a stroker landed in my lap. I believe my case is straight now. It has the thick registers (which I also believe are straight) and the updated oil stuff. I could probably be talked out of it if your case proves bad... Coming up might be a good idea. I can show you how to do valves and hand lapping. If you had the new springs I could finish heads. If you got real lucky "minimum" might be this. Bearings Rings Gaskets Roll pins Cam Lifters Push rods EF adjusters Springs/retainers/locks Those linked pics are good to look through. AT one point you can see the RMS drain mod. It's a FREAKING trench in that engine. On that one they went BIG! |
