HSR/gmhot cam or HSR/1.6RR...HP estimates?
87 stocklong block 350TPI
GM hot cam and HSR over setup i have now?HP estimates
HSR and 1.6 roller rockers over setup i have now? HP estimates
custom ramair, airfoil, completely ported plenum and portmatched to SLP runners, ADJ FPR 50psi, motorvation TB spacer, Motorvaton Strip chip, march pullies, no AC/smog equipment, headman long tubes, custom 3" exhaust with 3" xpipe and turndowns. MSD blaster coil,MSD cap and rotor, Accel ignition modual, VG2 plugs, mallory wires etc.
how much should i expect with the HSR over my modded TPI? i kno the stock cam runs outa steam at 4800 and the HSR wont make power till then. also thinking of doing the HOT CAM or just adding 1.6 rollers to the stock cam for some extra kick. stock L98 heads max lift is .480 so the hotcam with 1.5 rocker is .492...so i would prob have to do compcam beehive springs... anyone running the HOT cam with stock L98 heads? wat did u have to do for it to work? also will the motorvation chip work with the HSR/1.6 RR combo or the HSR/hotcam combo? or will a new chip have to be burned? need feedback fast, gona start ordering parts soon, thanks
