I'll look through the stash of magazines at home...

I remember reading in an old Mopar Muscle magazine some years ago, that a 318/360 Performer intake with a simple port match to 360 intake port size and a one (1) inch open spacer worked almost as well as a Performer AG intake on a standard stroke 360 combo (400-450HP) to 6,000RPM. Almost... I...

Never quite thought of it that way 273. You actually can't compress what's not there, great point!

Oldmanmopar, I have a 67 Barracuda with 8-3/4" rear and Kelsey Hayes discs up front. I'll like to go big bolt pattern as well, are the mustang rotors a bolt in with the existing calliper assemblies? Can you please provide some more information?

I'm with Rusty, pistons are sitting proud of the block a fair way. Measure accurately to determine static comp, then do the math to work out dynamic comp using a cast open chamber head. Should be around 9.5 - 10:1 static, with 8:1 dynamic comp, that will work great with the MP 484 cam and pump...

Thanks HemiSSDart, I know the 14x5.5J wheels fit both drum & disk, but what makes the disk brake wheels different to the standard 14x4.5?

Just wondering what's the difference between a standard steel wheel for a drum-brake A Body and one with Kelsey Hayes disc-brakes? I have a 67 Barracuda with Kelsey Hayes brakes up front and looking for a set of OEM steel wheels to go back to the stock standard look with wheel covers and red...

As a side note, I took off the Edelbrock 600 carb I've been running last night and installed a nice Holley 600 DP I had. Runs great, idles better and seems to make a little more power everywhere, judging by the 'feel by the seat of ***' meter. I also have the original Carter AFB 4924s & cast...

Thanks PRH, I'll check tonight.

273, I bought the 67 out of Canada in 2020 and had it shipped to Melbourne, Australia. It was in fantastic condition, the 273 was rebuilt some time back and ran well, except that someone installed a big duration hydraulic stick that sounded great, but was really soft on power off idle and...

PRH, that's really interesting that you have experienced something very similar to my situation. I'll take a photo of the offending cam lobe tonight and post for your reference, but I seem to remember it had a wear pattern across the whole width of the lobe peak, not sure on the flanks or base...

Thanks all for your good feedback, I'll definately check No.5 exhaust lobe with a vernier to compare to the other lobes. Bewy, I do have a set of old, used hydraulic lifters to I will send to Clive Cams to resurface. I might just give them a call and see if they can check / repair the associated...

Hi all, I have a 67 Barracuda with a 273 Commando mill. Before I got the car someone else replaced the original camshaft with a larger duration HFT. This didn't work too well for me, so I replaced it with a Comp XE262H HFT stick around two years ago. I noticed recently that there was a slight...

318willrun, I watched your budget 318 hop-up videos where you got your Duster running 13.90's with $500 worth of parts etc. This was great content, inspiring stuff. With this upgrade you ported a set of small port, small valve 675 heads. I'd like to know what difference there is in doing...

J heads come in around 64cc with a 0.040" cut, they were 72cc before milling.
