The larger exhaust port is a plus (and great if it flows well.) If this is on a performance 5.9, I would suggest 1-3/4 headers with a performance cam. 1-5/8 will work very well for stock to moderate builds.

A 10-1 ratio with an aluminum or iron head will be just fine with 91 octane and provide enough compression to use with some pretty hot cams for the street.

Cheaply done? Run a LA cam and do the math on the new lift. The cam specs I can write about later when I’m home. BUT! A duration of not more than 218 with a stock converter and a smooth idle is a wider LSA like a 112, but it’s a low end power looser. A tighter one makes more torque but less...

You can get away with another point to point and a half of compression and still run pump fuel. In example, I run a 11.5-1, 360, Trickflow heads and a Hyd roller @226@050 on 93 octane. Watch your timing. You will not require a lot of total timing under load. (Floored gas pedal)

Use a cam with as much lift as the heads can flow (or try to as much as possible) and run the Edelbrock heads. You’ll be miles ahead in the power game.

I can not actually say. If the big block guys had issues as well, they need to chime in. I mainly focus on the small blocks. If the other brands had issues, I do not know about it. I run a 11.5-1 360 with a Hyd roller cam 15* smaller than the written 241@050. 226@050. The fuel is any gas...

@matthon My ‘79 Magnum is currently, what I’d called, pretty quite with the ability to speak at a slight up tone in the voice. Bare metal floors currently. Carpet and sound deadened will go a long way. Hooker 1-3/4 into true 2-1/2 duals with long Dyno Max super turbos. This will be addressed...

Agreed. I had a 2bbl. 318 Duster with a manual 3spd. Deep first gear as well. 3.21 gears and stock tires. I found that racing the first gear up high is just like you said. IMO, you have the non experienced over play the deep gear and big drop into second as a really bad thing. I didn’t find it...

The aluminum OD case transmission is not for hot rods. They are best used behind stock and stock ish engines looking for light weight and mileage. There is nothing wrong with them per sai, just aluminum is easier to trash behind some power. Also the gear splits of the OD transmission is a bit...

Because not everyone is on the internet picking up the latest news on people reporting on the internet of their broken/failing parts if, IF it gets reported. Also as well if, IF the person reads the report that may only be found on one forum. How many MoPar forums are there? Do you read them...

That and his 32 miles to the gallon….

There are several 4 speed transmissions that all have the 1:1 final drive gear. One of them has the low first gear if memory serves. The ratios are on line. What is it your looking to get from the swap? I’d speak with Dan Brewer myself. Actually, I have and will again. Anytime I have called...

I have found that a 3.21/3.23 or better, a 3.55 is best for a street strip effort ratio with the low first gear. Any rear end ratio higher will (IMO) need a taller than normal street tire to help offset what becomes an extreme first gear ratio. Lower than 3.21/3.23, the cars final drive gearing...

FACTS! Even turbo cars that can run 9’a and 8’s are not out and about as everyday cars. It’s mostly just not practical. While I know a few people that run around with insane power, they don’t use it a lot. (The cars power)

Ditto Ditto. Enough lift to take advantage of the heads flow capability. Or at least try. That made me wonder how many people are going to try to go for that as well and the. How many machinists will have to explain it all to them. That was exactly what I was thinking. What the heck is...
