Just got my new h-roller cam from Oregon Cams. Now I can begin the assembly and move towards getting this thing going.

360 LA
Speedmaster CNC heads
Oregon h-roller cam 236/248 @.050, .539/.558 lift
Holley street dominator intake
750 Holley vac secondary

Should be a beast. Very similar to mine.
Start saving for tires.
 
Nice! I'm building a 360 also, been thinking about buying heads because mine has smog heads and I don't know if it's worth plugging and porting them. Post pics of the progress you make!

If all goes as planned this winter I want to remove the hydraulic lifters from my 340 build.
Why did you pick a hydraulic roller?
Who's lifter are you going to use?

The engine is a 1990 h-roller. We'll see how the stock roller lifters hold up.

I plan on using factory roller lifters on a similar build myself. Keep us posted! Do you happen to know at what aprox. lobe lift the oil groove on the lifter is exposed?

Sounds like a nice combination! 450 horse? Just a guess.

I ran the combo through Desktop Dyno and it came up with 400 HP. But to be honest, I wasn't really interested in the actual peak numbers as you have to take the software numbers with a grain of salt. I was MORE interested in the power curve with this cam which I think the software can compute fairly accurately.
 
512-do you have a roller block?
stock lifters are good
most short hr will be longer than a ft for the same area
(just like using a .842 ft profile vs .904)
except for jones inverse e=radius hr profiles
regrind hr makes sense
find a 92-95 318 magnum core if you can use electric fuel pump
core choice is critical for regrinds or base circle gets small and you may go through heat treat

Nope, my block is a 1969 LA
So I am currently using retro-fit hydraulic rollers - junk.
Worst recent mistake I made was letting myself get talked into using a hyd roller.

Got some figures for you.

From the top of the lifter to the top of the circled orifice is .826". The lifter had to have .46" cam lift rise to expose that same orifice measured from to the top machined surface of the lifter bore.

Dart_68, I’m working on a 91 roller block and wanting a hot street cam. Did you have your stock cam reground or is it new stock? I have the H116cp flat tops and probably going to use my J heads. The 308’s are cracked at least one is for sure that I know.

1.5 or 1.6 rockers?
