I scored an older 800cfm aftermarket thermoquad spreadbore manual trans carb. I want to put it on my 383 with new Eddie heads and Eddie rpm performer intake. Do I need an adapter spacer to fit on the manifold?

I’m replacing my standard hyd mopar flat tappet lifters in my 383 with rhoads hyd flat tappet lifters. The installation directions are confusing to me at one point. It states to set them up by determining when the pushrods just start to compress down ever so slightly on the cup within the...

I’ll explain a little background on this situation so that it is easier to diagnosis my possible issue. First let me again thank all of you that have helped me within the last year while I was tackling a lot of suspension and engine work on my 67 dart. I have learned quite a bit from all of...

I’ve come to a point where I feel it best to ask the peanut gallery. After a long learning process and overcoming many issues thanks to everyone’s help on here I have to make a choice. The 67 dart is back on the road and seems to be running fairly well. The issue I noticed is that three of the...

“I moved this update to a this new thread because I wasn’t getting feedback on what to do next in this situation.” I recently took my edelbrock performer rpm intake to a machinist I trust explained the situation to him and had him mill my intake .040 on each side. That is the same thickness as...

I’m trying to get my aluminum edelbrock performer rpm intake to line up and bolt down to my aluminum edelbrock performer rpm heads. The engine is a 383 and I don’t believe the deck has been milled at all? Not positive about that because I didn’t build the motor when it was done about 20 years...

I’m asking this question because I often get confused as I’m attempting to fix/upgrade/repair my 67 Dart. Currently I’m installing a new timing set and chain due to chain slack/wear. I noticed in the Cloyes timing gear set I ordered there was a three bolt cam gear and a cam thrust bearing...

I’m looking to replace my cast iron water pump housing with an aluminum upgrade. It’s going into my 67 383. I’m hoping to find an aluminum replacement that is as close as the OEM cast iron but lightweight aluminum. I’ve heard of some people switching over and pulleys not lining up or the...

I did some research on my own but am at a loss. I know the gurus on this site will have a solution. Ok so I posted another thread explaining that I’m taking out my cam to get it notched then putting it back in my 383. I’m also upgrading the heads, geometry kit for roller rockers etc. I...

Im in the process of reinstalling my cam after having it notched for better oiling. When I pulled off my timing chain it had a little slack in it. Is some amount of slack ok in a double roller timing chain? If so how much? Also is it good insurance to just put another double roller chain in...

Im on a tight budget after all the upgrades I recently did to my 67 Dart. Therefore I thought what performance upgrades could I apply to my 67 383 formula s at minimal cost. The original 383 engine as far as I know has never been apart and has great compression and uses very little oil. I was...

Everyone thanks for the feedback. Here is my situation right now. I worked with Mike at B3 racing super knowledgeable guy and very patient. Big kudos to him. He just sent me my geometry correction kit for the swap of my Harland sharp 1.6 roller rockers. I’m moving them from my old 915 cast iron...

So I already swapped out the drivers side of my 383 engine’s 915 heads and upgraded to my edelbrock performer rpm head. It’s all torqued down to spec and I can’t get the Harland Sharp rockers to fit all the way down on the edelbrock rocker pedestals. I took some photos of the problem. You can...

It appears as if I have to install the 2 rocker studs along with the hardware included on my edelbrock aluminum performer rpm heads. In the installation instructions it doesn’t explain specifics on what hardware goes where when installing the studs, washers, nuts and what appears to be spacers...

I’m planning on doing my first head swap on my 383 in my 67 Dart. I’m going from 915 cast iron to aluminum edelbrock performers. I’ve watched a few instructional videos on YouTube but still have a few questions. I though I’d put some questions out there for help. I’ll be swapping my Harland...

First let me thank everyone on this site for all the help and feedback recently. I've decided to do just about everything on my car's myself. In the past I would attempt some mechanical challenges but nothing like now. Rebuilding entire front suspension, swapping out TTI headers for tri y...
