When ordering the solid lifters, do you just ask to have edm holes cut in or are some aready cut in . What would be a good company to contact for 300 lifters with edm holes
Also looking at double valve springs rather than single Beehive springs.
A single Beehive spring does have advantages over a regular single spring but we still had problems with an aggressive hydraulic profile cam with Beehives.I had the understanding that the beehive design in itself would help with valvetrain stability. and provide the needed spring rate.
Yes, you would order the cam and lifters first then determine the valve spring specs.Ok would I order the cam and solid lifters first, then the valve springs to match cam lift and well push rods last. If so which cam should I be looking at or ordering, you seem to speek very highly of Jones cams.
Yes, you would order the cam and lifters first then determine the valve spring specs.
Once the head is on, you figure out the rocker arm geometry which will determine the pushrod length.
If Mike Jones has cam cores he would be a good source for cam and lifters.
Crower cams would also be a good source for the cam.
Looking for peak torque at 4000 rpm to make good upper rpm power but still have good turbo response off the line.That was an intake and exhaust lobe .050 duration at around 240 degrees and a LSA of 112 degrees. Flat tappid cam . how much lift would that be with 1.6. Or the 1.73 Roller lifters And we’re would peak torque be.
Just looking at Comp and Crane double valve springs, I see springs set at 1.800" and with around 400 lbs/in with coil binds closer to 1.150" or less.The .550 value lift sounds good , if I remember valve springs and lift , with the set 1.800 Val. Spring height set , with the longer valves the max lift possible should be around .575 before coil bind and or valve train problems. I have been thinking about 5700 to 60- 6200 RPM level
