Another 440 Build Question...

[1967_Joe]

Here is what I have...

Engine work completed at the machine shop
'67 440 bored .030
line bored, decked, etc
had brass plugs and bearings installed
Edelbrock performer heads

My intentions are for street use only - weekend mauler (torment chebbys)
727 tranny (8 3/4" rear - gear ratio TBD, have a few options)
Yes, want it to run on pump gas and I want it choppy - Joe Dirt!

Suggestions for piston/cam combinations?

Stroker kit. anyway... I use Diamond pistons, Total seal rings, Comp Cam hydraulic cam gross valve lift .538 intake and .534 exhaust. I cheat with Solid roller lifters on the hyd cam works good just get the right pushrods and don''t over tighten.

base HP 535 with 650 ft lbs of tq @ 3200 rpm all based on camquest software projection.

Personally I think it's more this motor is a rocket and idles like a car lining up to drop the hammer at the track but cruises the family around like a puppy. 3" flowmasters don't help lol but sound bad *** and scares the **** out of people when it first fires up lmao!

509 Hydraulic!
Sounds really mean and choppy in a 440.

What pistons and what is the compression height of them? Need to know what your static compression is before making a cam recommendation....

Is it goin in a ten ton school bus or a Astin Martin? Would be nice of folks to let us know this stuff before we start slingin out useless recommendations. Cause that's what any recommendation is unless you know what it's goin in and the approximate weight.

 

[1967_Joe]

It is going in a '67 Plymouth GTX (might as well be a 10 ton school bus :headbang

Use the Mopar purple .455/.455 cam. I have it in my 2wd truck with a 440. Truck weighs about 3800 lbs. Has stock converter. Its a conservative cam for a heavy vehicle.

I have it in my 66 Bel with a 440. 3900 lb going down the track and with 3.55's and street tires it ran low 13's @ 109. Best ET with slicks is 12.80. It has a nice rumble to it and with the 3" noisemasters it draws attention. Compression is 10.1:1 and requires premium. Best of all is the build was cheap, the motor will live for a long time and is extremely streetable.

That's sweet. I have slicks on mine hoping to squeeze some low 13 pass's out of it. Although my compression is sitting around 8.6-1. But ya, very street able and will be a reliable good runner for years.

Dont run a sissy *** cam (no offense Meepomous) with aluminum heads capable of .600 lift and 11:1 compression on pump gas. That's like rentin a 10K dollar hooker and not even gettin her nipples hard.

What are those heads open or closed chamber? If they are open, run a domed piston, get compression up to 11:1, run a BIG flat tappet solid 260-270* duration @ .050, or a moderate solid roller 250-260* duration @ .050 around .600 lift and 110 LSA and there's your pump gas "mauler".

Geez, are yall seriously recommendin this guy run a .455 lift cam with aluminum heads? Really?

That's like rentin a 10K dollar hooker and not even gettin her nipples hard.

This has to be the QUOTE OF THE YEAR!!! :headbang:

 

[1967_Joe]

Let me ask one more question...what if I went with the standard 915 heads? How would this change the piston/cam combination?
