Roller Rocker- Scorpion was a disaster. 2 rockers were made wrong and they split in half. I have a used complete set of Scorpions for sale with new replacement rockers. I went T&D all the way.What is everyone doing for roller rockers and shafts?
$1500I run scorpions on my GN1s for 8 years no problems. The shaft mount T&Ds are nice. They just cost a lot more. When I last looked they were $800 and that was years ago. Not sure what they cost now.
for irons or GN1?HARLAND SHARP.
Bought 2 sets. Not building a backup engine, as I got too good an offer to pass up for the car. I'll split the shipping. Still in original packing. 1.65 ratio.
So far I purchased the champion iron CNC ported heads, got a cam from Bison, GN1 stroker kit, and converter from Dave H.I thought the OP was planning on GN1s unless he changed his mind.
But if irons the HS are good.
I have the 214/214 Roller Cam from Full Throttle with Ported Irons and the Harland Sharp 1.55
Lift is 0.330/0.325 duration is 218/212 on a 112 lobe seperation. We are going with 1.60 rockers.I have the 214/214 Roller Cam from Full Throttle with Ported Irons and the Harland Sharp 1.55
the extreme energy lob is a nice lob.It is more than I would run but Bison is the man. And in the famous word of Larry GETTER GONE.Lift is 0.330/0.325 duration is 218/212 on a 112 lobe seperation. We are going with 1.60 rockers.
There’s a trade off between overlap and richness. More overlap will require a richer idle in order to be stable, as well as more speed. More displacement and more static compression helps idle too.What does everyone's car idle at with a roller cam? Right now I can get my stock motor with 120 pound injectors to idle at 800 rpms. Just curious if its possible to get a cammed car under 900?
