Default bushing instead of adj. T chain? also question for cam experts.

doesnt "search" work anymore?

anyways Im installing a cam and degreeing it, checked it 2 times, exactly same result. ICL of 107.5. needs to be 110.

does anyone sell the bushings like the old school small blocks where I can just drill out the cam bolts/dowel hole and install the bushing to rotate the gear back?

Ive used a cloyes hexadjust before, and they work great but the're expensive. Id rather see pops spend the extra $150 on something else if possible.

and, for the questions. how much would the current centerline affect the power band? as in would I gain/lose power? it would shift the max power rpms down to lower rpms right? how much do you think? Im goin to measure PTV clearance like this hopefully tomorrow, how much do you think it will lose in clearance by haveing the cam adv. 2.5deg.s from where it should be?

Make sure you are degreeing it right a 108 intake lobe center and a 112 exhaust means a 110 LSA


Don't drill all the way through like the instructions say I measured the depth of the bushing and drilled enough to get it flush. The tip does not go all the way through on the LS1 camshafts I have and the outside just holds it in. The bushing hole is 13/32 I only drilled the bolt holes to 3/8 because I'm not shooting for 8 degrees advance or retard. Mr gasket makes the kit and sells them in odd and even sets.

sean, you gonna stop by? know what house is mine? I'll be home tomorrow after work around 6pm.

stunning man, thanks for the pics. and the info. I used the ICL method. never done it any other way. my LSA is 112+2. doesnt that mean my ICL is 110? but the seperation is 112? doesnt that mean max lift is at 110deg. for the intake lobe? maybe Im getting lost here. should I be measuring the exh. too, then averaging them out?

chris

you still install it dot to dot, but your shifting the position of the cam behind the dot a minute amount. the biggest reason for doin all this, instead of just putting it in and goin with it (which is what most people do) is sometimes the cam manufacture's will not get the cam cut exactly right, sometimes the dowel pin isnt exactly where its supposed to be, and sometimes a crankshaft has the keyway cut in a not exactly right position. so basically your checking all that stuff, and making up for whatever your tolerances stack up to. alot of times it will be 1, 2, or 3 deg.s off from where it was intended to be.
