Nice deal for some really up to date hardware. I replaced the valve springs with Comp 26094's since I'll be running a .600 lift street roller cam. Just waiting for the new Super Victor intake to show up and then we're off to the dyno. 4368548-505.jpg (1030 downloads)

They weigh 22 grams which is only 2 grams heavier than Ti retainers but they are a lot cheaper. Also, they hold up to flat wire dampers better than the Ti retainers. I'll probably start using these retainers in any motor that takes a dual spring. 4368553-retainers.jpg (861 downloads)

The MCH ported heads and I'll be using the Super Victor intake and a Dominator. Comp rocker arms with the 1.50 ratio but I might try a 1.60 rocker arm just for fun. The valve springs will handle up to .650 lift so I might do it, just requires a new set of pushrods and an extra hour or so on the dyno. I think I'm going to try these Edelbrock head gaskets but I'm worried if the bore is big enough. If it isn't I'll have to come up with another plan. Maybe reuse my Cometics from the last dyno test since I know they work. Compression is around 12.5 so she'll probably make some power. Should make plenty of torque with the tiny ports and the small cam! 4368571-top_end.jpg (814 downloads)

I used those retainers in w2stroker's engine that made 685HP with a sizeable roller in it. Worked very good. I agree, I think they are the only way to go. Brian Brian Hafliger

Another nice thing about these retainers is that they are quite a bit thinner which means more clearance for the rocker arm. I guess that Manley is also selling this same (or similiar) retainer now so it must be catching on.

Actually you need three turned down for adequate oil flow with the small T&D shaft but the end ones do not need to be turned down since the oil doesn't flow past them. I bet T&D provides the whole kit turned down since they don't trust their customers to assemble the setup correctly. Last edited by AndyF; 04/19/08 01:51 AM.

Taking pics of them today, and sending them off..How much do you think they would need to be added to fit them on an engine in a car ?? From: AndyF Hi Rick, I measured up the wires for the Jesel belt drive distributor. The following lengths should work pretty well with dyno headers and Indy heads. The wires will loop down under the heads which works great on the dyno but might not work in a car. 1 wire at 24 inches, 3 at 33.5 inches, 2 at 38 inches and 2 at 41 inches. The Jesel distributor has HEI style terminals. The wires need to have 90 degree boots on both ends. The measurements are from center to center of the boot. (center of the spark plug to center of the HEI terminal) Join the quickest team in motorsports. Team FireCore. CustomWiresets.com

Specs on the cam are 260/266 at 050 and .588/.597 lift. The MP .590 is 265/265 and .590. But based on how these lobes look I've got to assume that this street roller has a ton more duration at .200 and .300. I'll measure it just to see. 4369829-roller.jpg (422 downloads)
