273/279 duration is that at .050I've been takin advice wherever I can get it, but It's conflicting. I,m putting a stick in her but I think I have to much cam. forged machine shop balanced with victor high rise, torker cast iron heads. close to 10.1. lunati 575-578 and 273/279 duration. heads ported to intake, ran 1/2" fuel line so fuel is no issue other than the sorry state of pump gas. I don't care about idle just want her to scream. so Too much cam?
help 383 build..

yes duration is at.050, with 1.6 scorpion roller rockers, cam is a solid roller. thanks for any input.
yes, but it,s still in the box, can be returned if nescarry, summit thinks I, crazy anyhow.
So duration @ .050 (Int/Exh): 243/249
yes I'm looking at the spec sheet. your right.
Some AFR 190's will make it nice combo.
Close to mine. Mine is Lunati hyd. roller 560/565 - 243/[email protected] and I run some AFR 195's on my 383.So duration @ .050 (Int/Exh): 243/249
i agree, some AFR 195s with that would make for a very stout street motor
I run 2.02 Brodix heads 10.1 383 40 over with 1.6 ultra pro magunm roller rockers and roller lifters and roller cam 576 lift i love it
thanks
thanks for the input, I just didn't want to be stupid. on another note I Hate those @#!&^ spirial locks on the spotsman pistions, I know they are good but infuriating, thanks all for the info.

I was told to spring them out a bit by stretching them(where they will stay sprung out a little on each side). Done it that way a couple of times and it is easy to get them in. They fully seat and lock in as supposed to. A machinist told me that and it works for me.thanks for the input, I just didn't want to be stupid. on another note I Hate those @#!&^ spirial locks on the spotsman pistions, I know they are good but infuriating, thanks all for the info.
I can testify to that.:yes::yes:i agree, some AFR 195s with that would make for a very stout street motor
:yes::yes:
my 383 cam is .544/.544 @ 246, with 195s... ohhh, so fun :yes:
i run that camshaft on my 383 with afr 210 heads.1.5 scorpion rockers.love it
-Do you have correct springs on the head to accomodate needed spring pressures?
-And with 1.6 rockers your lift is ~ .616. Can you handle the lift without coil bind?
-Adequate piston to valve clearance?
Just something to make sure so you don't run into problems.

trusting my machinist on the springs, picking up heads in a couple of days, will check for valve clearance before final assembly, my pistons are dished so it shouldn't be an issue, my machinist (Mark) also got me my rotating assembly, was going to by kit but most have 3/8' instead of 7/16' conecting bolts, went with iron eagle crank and scat rods, have my push rod length checker in hand hoping they fall into an "off shelf" length.
I went with the Scat I beam rods with 7/16" ARP rod bolts. It's hard to beat them for their $300 price tag and still rated to handle up to 750hp.trusting my machinist on the springs, picking up heads in a couple of days, will check for valve clearance before final assembly, my pistons are dished so it shouldn't be an issue, my machinist (Mark) also got me my rotating assembly, was going to by kit but most have 3/8' instead of 7/16' conecting bolts, went with iron eagle crank and scat rods, have my push rod length checker in hand hoping they fall into an "off shelf" length.
I want to say my pushrods ended up being 7.100. I think a factory (hydraulic)roller is 7.200 long.
yeah the scat I beams seemed to be the best way. The forged Iron Eagle crank was a bit pricy but machinist said It was much easier to balance than the scat crank. from what I've been able to come up with this motor is not going to start breathimg good till around 3500 rpm.
