In keeping with the NA….
Let’s compare flow numbers and port velocities.
This is a camshaft related issue, not cylinder head.
It is true. The better the cylinder head the better the power. A higher flowing cylinder head over stock allows more power and rpm.
While the OEM - LA head gets buried deep on this front, what do we have to replace it and compete? I can name 4 off the bat.
But yet! There a roller compared to a standard solid which is an edge. Mostly since MoPar guys cry at the thought of a roller cam.
The LS has a lifter bore size of?????
So in the past when our old time racers spun 8500/9500, it was black magic that we can’t reproduce suddenly?
Just wondering.
The modern blocks are better OOTB then ours from yesteryear.
And that’s where it stops.
There architecture is better and the advancements after 40/50/60 years is apparent. But let’s dumb down a modern engine and cripple it with a wet flow intake and 4150 carb, stick it with a SFT and see where and what we get.
No one owning these engines would ever do that and it’s a crying shame any old time engine guy has major fears and sudden cash flow problems in meeting what the others were born with. I get that. A roller cam, F.I. & OD transmissions are expensive and prohibitive to 99% here.
But if your going to compare engines, think before you speak on who has what in any real advantage and what can not be modified and equaled.
Hey! Didn’t Brett Miller make a 1,000hp NA SBM?
Currently being raced by the way.
YeAaaaaaaa, well, there’s that now huh?
I tell ya it’s a danm shame I don’t play lotto…..
