The eng has a 750 edelbrock, everything else is all stock (flat top pistons, 906 heads etc) its also an automatic torqueflite and a 3.23 surgrip BTY the motor is in a 67 satellite

If you just want to lighten up a bit, and have the look of an aluminum manifold, an Eddy perfomer might be the best choice. It's basically no different than stock, just cast in aluminum instead of iron. Personally, I'd go with headers instead of manifolds. No other bolt on part (sans a nitrous kit) can match the overall performance gain of a set of headers. I guess the real question here, is: What is your long term goal with this motor?

If that's the case then a performer rpm intake and headers would make a weight reduction of a 100# or so but would make make a huge performance gain if the engine is a stock 383hp. Al & Sheila

I've weighed the parts so far, and here is what I got. All 70-383HP stuff vs. the aluminum parts chosen. Iron: Heads: 50 lbs each W/P hsng: 16 lbs intake: 38 lbs Carb: 10 lbs EX. Man. 16 lbs each Total: 196 lbs. Aluminum: 440source heads: 30lbs each CH4B intake 10 440source W/P/H 5 TQ Carb/adapter 5 headers 15 Total: 95 lbs. Luckily, the only things I have to buy new are the heads and waterpump housing. Everything else was used on the aluminum side. Still cost me apx. $1200 to save a 100 lbs on front of the car. The bright side is...i was thinking of building a set of heads anyway. Why not buy new.

Probably about 40hp on a good intake swap and headers. Mopar Muscle did a stock 383 HP rebuild and then added intake, carb, headers, etc, to the stock short block and got 450 horse total, which included a cam swap too, but otherwise a stock 383HP. The stock type intakes are: Weind 8008, which is real close in appearance, Eld. performer 383, which accepts a TQ carb, and Eld. DP4B, also very stock appearing. A Eld. performer is good, or RPM, but may cause hood clearance issues. Other things to look for are your radiator, which is probably 25 lbs dry and starter, which is 15 lbs. I just weighed them a while ago. An 054 Rad. and stock rebuilt starter. Look for bargains here, ebay, craigslist, etc.

I have a set of Year One 69 Hi Po exhaust manifolds and they are cast iron and weigh the same as factory. I have Hedman Hedders, a 750 Holley DP and a Edelbrock Torker intake on my 69 and like how it runs. 77 Macho Power Wagon LWB factory 440 70 Coronet 440 N code 3 speed
