Headers for 1975 360 LA for Dodge M37
Looking for shorty headers with 1 3/4" to handle 500-550 hp, was told shorty headers with 1 5/8" were too small.
Have not found larger primary tube shorty headers, placing in an old 1952 doge M37, and do not have much space.
I am hooking up to Edelbrock 60775, heads.
Any suggestions ?
Thanks

Welcome to the site Del..... Sounds like a great project. I'm going to suggest you find a local guy to see if they can build some custom fabbed Headers to fit you application for the truck. Good Luck... Keep us posted...

1 5/8 are small but will cost you less power than you think, shorty headers will hurt you more.

Welcome.
With 1.4 to 1.53 hp/cubic inch we're looking at a high end performance, high rpm engine. To maintain that I'd be wanting 1 7/8"- 2" O.D. long tube, tuned headers.

for his Dyno testing, may need to buy a cheap pair then pay for custom.

Maybe you could barrow a set , you would think that he would know a mopar guy.

I asked the same question, but not a lot of guys run mopar engines. I am adding a Holley sniper EFI carb and just bought CVF front pulleys.

I just noticed that piston with 1.457" compression height is for a 4" stroke crank 408 c.i., looks like a cast crank too. Calculates to 9.7 c.r., sound about right?

We added a scat cast 4 inch stroker, mechanic was thinking better metal than a few others with APR studs. The cam was custom still need to find more detail numbers were not on my billing sheet.
