If my builder recommended that cam (a safe choice) I'd get a new builder
Readjust the valve closing......I’d put that in at 109 and not 106.
You don’t know what cam the op got?rumble
we don't know if the builder picked the old h or the newer hl
that h predates UDHarold
but customer ended up with the hl
IMHO cranes were smoother good for U
not a magnum I take it
The hr regrinds seem to work well
We got the rotating assembly back finally. Ended up right at 10:1 compression. DCR calculates out to 7.9:1 with the comp xe274 cam that the builder recommended. Should be quite the runner all said and done. We have a tc coming from ultimate converter with a stall in the 2800 to 3200 range. Do any of you have experience running a holley avenger carb? Thinking well slap on a 670 avenger.
That's nice to hear. I've got a new XE275HL sitting on the shelf and was thinking about putting it in my '71 340 when I swap the J-heads out for ProMaxx 171's with 1.6 rockers. I've got 3.55 gears and a 2500 stall so it sounds like it might make for a decent combo.That's the one! NOT XE274, it's mediocre if you want a fast acting lobe. As Wyrm will tell you, there is something to be gained from a .904 specific grind, as long as you're OK with potential wear/noise issues over a slower lobe. I personally like the XE/HL series, and have run them myself. Put the 258HL in my 440 and used a 275HL in a MoPar crate shortblock 360 (took the .508" Purple cam out) with OOTB Eddy RPM heads. Nice combo, with a LD340 intake and 3.23 gears/2500 stall in a '72 Duster.
Thank you!, though post #36 has nothing to do with what cam it is.see post 34, 35,36
We have the machine work done on the 318 finally. The builder is wondering how high we want to go with the compression ratio. He is suggesting keeping it around 9.6 to 1 with the dishes pistons. Were wondering if we should push it over 10 to 1 while were at it?
Kinda depends on your application and planned operating rpm, cam, timing and other stuff that requires vacuum, eh? (A nod to America's hat there...)
Your money, your build and your smiles per gallon...
