Rocker arm ratio

[Obwonkonobe]

I have a stock 78 c10 350 motor, standard stuff. I was wondering if it would be doable to up my rocker ratio to get more lift. Im pretty sure I have a stock cam and rockers. If anyone has had any success with this feel free to recommend a new ratio brand etc, thanks

If you want more lift and actually want to notice the power increase, you would need to do some porting and especially unshrouding combustion chamber around the valves. And then without increasing the duration I'm not sure you would notice anything.
Also I don't think I woud take the chance of increasing the stress on the lobes, lifters and rocker arm posts of an older engine.

And so near the end of the vid they are talking about the extra power that was gained by the rockers with higher lift ratio...
1st thing were the heads, those heads FLOW. Your stock heads especially the exhaust side, not near as much. And were was the extra power gained hmm? Somewhere over 5k rpm.

Really, if you want more joy from the loud pedal don;t piss time and $ away adding things to your sb... just go BIG. BBC! There is NOTHING in this world like big block cubic torque.

He did say it was the heads that made it possible. And the stamped rockers they used were a bogus comparison. They should of used true stock rockers. Not a beefed up 7/16 studded aftermarket one. Then they put 3/8 studs in to test the roller tips, another bogus comparison. I call ********.

He has a little more at stake the 2 monkeys that are given free parts. Gee I wonder who really sponsored that episode........maybe Scorpion. I’m not bashing Scorpion, I had a set of the self aligning kind on my Vortec heads and they worked ok I guess. Other then busting off the drippers on my Vette valve covers.....I guess I may be part to blame for that though. Lol

Scorpion is ****, built a 468 for a friend's family day cruiser not much more than a stock cam, 3 of them broke within 20hrs on the engine and it never goes over 4000r's and for very short bursts, finally I threw them in the trash and put a set of Crowers on, end of problems. BTW, each one broke at the trunion..
