Re: Mating Two V8's, ( Freight Train) vs. Harmonics

At the US Nationals a few guys ran dragsters with inline engines timed at 90-degrees with great success, couple of guy's tried 45 degrees and 45 shook like hell. The twin engines allowed the sbc go 200 mph , IIRC it ran 190 all day long on one engine.

Re: Ongoing Detonation Issue Help!!!!!

So what if anything can I do to alleviate this ring issue. Both detonation due to the crevice volume and the ring getting cocked in the bore are both good explanations. Both could cause radial ring flutter. I took 2 grams off the dome and line2line to help stabilize the piston. I had the intake and...

Re: 383 SBC Holley 750 eye burning stinky idle

It's been my observation of carb smells that when rich it will smell like propane / rotten eggs and lean would irritate your eyes and stink. JMO

Re: 350 Uneven Cranking & Won't Stay Running After Break In

FWIW if at first assembly you went 3/4 turn after zero lash and the lifters pumped up fully then around.031” multiplied by rocker ratio was added to valve lift at all points. Can you describe the type of clip that holds the lifter plunger ? is it a round wire type or does it have flat type with a h...

Re: crankshaft balance tolerance

Hi, question: how much gr difference is allowed from one piston rod combo to another in terms of balance? Hi Belgian , this is just my opinion , I have a balance machine so that issue will not show up in my shop , I don't have an actual engine to relate any facts , but if the piston balance weight ...

Re: SBC - main bearing clearance question

Belgain1979 , Why not use some .001 brass shim stock between the main caps and the block ? from the last pics I have seen that engine is just too tight , if you don't want to do that then a line hone is your next fix. JMO

Re: Exhaust valves leaking by

If I read your email right the good cylinders are leaking a 5% and the bad ones are leaking a 15% I would say run it. I assume you are just index racing, so just dial the time you want to run. I guarantee there are lots of engines leaking more than yours being raced every weekend. I agree with rebe...
