Re: Help with rocker arms
Comp = your paying 30% for a name. Same with all of the industry 'standards' like MSD, Comp, Moroso, etc.
I'm not saying their parts are inferior, just that if you place a $100 Harland Sharp rocker, and a $100 Comp rocker side by side, your getting a $90 Harland Sharp product ($10 name) and a $70 Comp product ($30 name). Just did a search through slummit and they apparently still have a good supply of the Crane Gold rockers. IMO these are the the top of the heap in stud mounted rockers. http://www.summitracing.com/search/B...roller+rockers As far as rods, I've used Scat rods and they are a decent piece. I'd much rather use a cap screw rod than the 'through bolt' style of the Eagle. Always offers more clearance to the bore and cam. If you do a search for 5140 vs 4340 you will find there is as many for and against either. The biggest question being the material testing and quality of either. These both are made in the same Chinese foundry as I understand it. The heat treat process to make the 5140 as strong as the treated 4340 causes more distortion in the forging. 'Could' be a point for a flaw, or not?? I'm not a metallurgist and really don't understand everything I know about the two. Both should be fine but for my money, the Scat 4340 would go in my motor. Better piece, better finishing, better material. $40 is worth it IMO.
