I'm freshening up a 1974 low comp 318 with a quick hone, new plasma moly rings and new bearings. I done some home bowl porting & port matched the 675 heads with larger 1.88 / 1.60 valves. SCR will be around 8.5:1 with Mr Gasket 1121G (0.028") head gaskets. Using a port matched Performer intake...

Has anyone built a 273 Commando or other mild 273 mill, with either a hydraulic or solid roller stick? Is there any real benefit to a roller stick in such a small V8? Hypothetical A Body 273 build to base this discussion on: 273 block bored 0.030" with a zero-deck flat-top piston (9.5:1 SCR)...

I have a 67 Barracuda Formula S with Kelsey Hayes front disk brakes. Can I get some feedback on the best complete front-end kit for this A Body. I prefer to stay with an OEM type rubber bush kit, not poly stuff. What do you guys think of this complete kit from eBay? Front End Suspension...

I have a 67 Barracuda with a 273 Commando and 4 speed. The existing clutch arrangement for the 273 is a 9.5" clutch with 9.5" 122 tooth flywheel. I'm looking to mothball the 273 and replace with a 'stock' looking iron headed 416. I need to go to the larger 10.5" clutch which requires a 10.5"...

I have a 67 Barracuda with a 273 Commando & 4-speed. It has the 9.5" bellhousing and clutch at the moment. I'm building a 340/416 with mildly ported J heads that I intend to paint Chrysler red with 273 Commando valve covers and air-cleaner etc. The motor should make around 420hp and 480tq, the...

I'm sure this may have been covered before, however l'd like to hear from people with direct experience. I'm building a 340/416 with mildly ported iron J heads, 9.5:1 static comp, Weiand Stealth intake, Carter Comp Series 750 carb, Doug's 1-5/8 long tube headers. The car's a 67 Barracuda with 4...

Hi folks, can anyone provide some specs regarding the last of the LA 360's manufactured between 1989-92. Looking to buy what appears to be a good running '89-92 360 motor, want to use a Weiand 8022, an AVS2 650, 1-5/8" long tube headers and replace the OEM hyd roller with something else. Any...

I have a 67 Formulas S 273 with Kelsey Hayes front disk brakes. Which type of OEM stock steel wheels are the right ones for this car. I believe there is a clearance issue with the KH front brakes?

Looking to get a set of Doug's D453B headers for by 67 Barracuda. Anyone have any experience with these headers, and in particular the ones with hi-temp black coating. I have two questions: 1. Does the hi temp black coated headers reduce heat in the engine boy (like ceramic coating headers). 2...

l'm after a nice set of wheel covers for a 67 Barracuda Formula S. Thanks.

Fellas, I have a 67 barracuda with a 273 Commando and 4 speed. About a year ago I installed a new direct replacement 10” clutch I got from Brewers Performance. Great fit, no issues, works great. I have the standard 122 tooth flywheel that originally used a 9-1/2” clutch, now with the 10” clutch...

Has anyone ever tried to port/gasket match a pair of OEM 273/318 A body exhaust manifolds? Any noticeable difference in power? I have a 67 barracuda with a 273 Commando mill, was wondering if I should gasket match the original exhaust manifolds or install the Flowtech full length headers I...

Does anyone have any images of a '67 273 Commando mill from back in the day? Publicity shots, or actual shots of the engines when they were new. I'd like to get an accurate account of the engines & engine bay. Thanks.

Has anyone actually built & run a 318 just like a 273 HiPo motor? That is, a 318 short motor with a nice flat-top piston that will produce around 10:1 static compression with 273/318 '920' closed chamber head, and the following 273 Commando parts: * Cast iron single plane 4BBL intake manifold *...

Looking for a good running 340 or 360. I'm looking for a complete motor, or a long motor. I would prefer something internally balanced. Let me know what you may have. Thanks.

Would full size 14" hub-caps for 67 Barracudas, fit / clip onto a 14" MoPar rallye wheel?

Hi y'all, Can anybody tell me if Doug's makes long tube headers for a small block in a 1967 A Body (Barracuda) with 1-3/4" primaries pipes? I've only found ones with 1-5/8" pipes (PN D453). I have a 273 Commando in the Barracuda, and I realise that a 1-3/4" header is probably too big for a...

Hi all, can anyone provide information on the following stamped number on the end of a small block Mopar hydraulic camshaft I have: RPD20 B1 7 I think it's a Mellings camshaft, but I can't find any more information on line. It was in my 273 Commando motor, and it had low vacuum at idle and...

I have a 67 Barracuda with Kelsey Hayes 4 spot front disk brakes. I want to go from 5x4" to 5x4.5" big bolt pattern (BBP) and was hoping that someone out there makes a replacement rotor that fits the Kelsey Hayes 4 spot caliper and has the BBP with 1/2" studs. Any ideas?

Hi all, I have a 67 Barracuda Formula S with a 273 Commando and 4-speed. For whatever reason the previous owner replaced the original cam with a hydraulic stick and stamped non adjustable rockers. I have no idea what hyd stick is in the engine now, the 273 has a really loppy idle so it would...

I'm using a standard single points distributor on my 67 Barracuda 273, it's a Formula S so it's a HiPo 273 4BBL. It runs okay with the points dizzy, but I decided to go electronic with a Mopar electronic distributor and orange box (the box is more than 20 years old and genuine Mopar unit). The...
