I want more power out of my 96 350 but don't want to pull the motor to do so if I don't have to as I dropped it in less then 6 months ago. Whipping shities on frozen lake lmao. But I have the heads from the old motor I already had them pocket ported and polished I'm trying to upgrade my valve train for power. And I know alot of people are criticizing me for adding power to an L31 2 bolt main but besides the point. Can I put in 1.6 rocker arms with my factory cam and still make more hp and if so what's my gain trying to decide if it's worth it or save up more and buy a decent cam which I plan on anyways but isn't in the budget currently any advice is appreciated
How Much? Not Much
Specs per GM Powertrain
OE Lobe Lifts are about 0.276" Intake & 0.285" Exhaust
w/ OE 1.5:1 RAR, Valve Lifts are about 0.414" Intake & 0.428" Exhaust
w/ aftermarket 1.6:1 RAR, Valve Lifts are about 0.442" Intake & 0.456" Exhaust
a net gain of less than thirty thousandth's valve lift; again, Not Much.
if you're lucky, duration will net about one whole degree more as well; Not Much.
*suggest more camshaft*
