Stock Cam vs High Lift Cam - Why You NEED Different Pushrods !!!!

LINKS BELOW
iv seen it far too many times! a big cam in an engine with stock pushrods. stop this madness!!! change the cam, change the pushrods!!!

DETERMINE PUSHROD LENGTH

SETTING PROPER VALVE LASH/LIFTER PRE-LOAD

[dobraydien]

This helped. Ordered a 278/204 intake, 288/214 exhaust cam. Cam card said it would work with factory pushrods. After setting the lash the cylinders had no compression. Backed off the rocker and boom, . Good compression. Reset the engine to tdc and rechecked the#1 pushrods. Sloppy sloppy. Love and learn not to trust manufacturer s' word....

Just wanna say thanks for sharing the knowledge. I feel like every video i walk away with information that makes me say hmm i didn't know that!

I built a 350 (388) and put a smaller cam for the street .550 lift, it used to be a roller motor. My pushrod legnth ended up being .250 shorter than stock. Also with the cam, heads were milled .020 as far as I know because I got them used, and .010 block decked. Standard felpro head gasket. I found a good used set of circle track pushrods on ebay for $29.95, CV brand, chromoly /hardended. Their walls are .110 instead of the standard thinner .080.

Hey there, I have a 72 F-100 with a 390 GT, it has the none adjustable roller rockers. Do each push rod have to go back to the same lifter? Or could in do new push rods with old lifters? There is a little wear on some of the push rods and some look to have very little wear.

Im putting a tfs 1 cam in my rebuild with a new TF spring kit on the gt40p heads. From all the research I have done the stock push rods should fit. Most were saying everything under. 550 was usually good to go. Thoughts? This was a junkyard motor that im rebuilding and I have definitely exceeded my budget haha. I will def try and check the length or look for any movement. I know the machine shop is going to put shims in if needed also.

211/220 at.050” lift 😅duration in 5.7l pickup on a 112 LSA. Heads flow 275cfm at .500 and 280cfm at .550 on the intake. 213cfm at .500 and 218cfm at .550 on the exhaust. The cam I chose has lift of .511/.517. My gearing is 3.73. Any chance thoughts on performance?

I do enjoy your videos very much. ive learned a lot. I do how ever have one request, if the audio can be amplified? or maybe a chest mic? my sound is maxed out and I cant really hear you very well.. only complaint :) great videos I look forward to the next

[speedlimitmph]

I'm guilty... :( E-cam, GT-40P heads with stock pushrods and roller rockers...oops. sounded like a sewing machine! lol.
Keep up the great vids man, I always learn something!

[danetbra]

Im sure youve probably had this before, but would you be able to get away with using the existing lifters with a new camshaft? The ones in my 302 now all seem to be in good condition with no nicks that i can feel with a scale on the rollers. for someone on a budget is it best to save up for new parts or will I be okay? Love the videos man! I learn tons

[limabravo]

I know this is off subject but can you use a solid roller cam with hydraulic roller lifters

[truthandjustice]

But anyways lol... what are the specs "Lift" of these two camshafts buddy?

[GR-RadioSouthCarolina]

The n271 cam that was in the galaxie you think pedestal mount rockers will be ok with that

[eddieallen]

do you work on Chevy's too? I got a stock 350 (early 70's) with 76cc heads and I plan to use 305 58cc 601 cast heads and I was wondering if I need to keep the 350 valve springs with that cam or if the 305 springs will do.

Hi, I have edelbrock performer rpm "right out the box" heads and there are few problems. One of those is that some of valves are sinked deep in seats and valve stem high differs a lot and rocker arms geometry all over the place. There are not much options for pushrod at length what I need What You can advice in that situation? May be I can make a special fixture to grind accurately ball pushrod end for every valve to achieve proper geometry? I cant grind valve stems for that much because rocker arms will be to close to retainers. Sorry for my poor English.

Hey thunderhead298 I saw a guy doing a review on his Motorized bike. And it was the Motorized bike u sold to a guy last year u know that 29 inch black bike with the black motor what u built. So just thought I'd let u know the guy who bought it off u has a review off it on youtube

[ravikannan]

Anyone please
I replaced my street bike (sohc)with 10mm lift cam instead of 5mm lift. But the results are poor than the stock. Upgrade big carbs too and increased the compression ratio also.
please support...
