adding '302 heads to a 318 motor ???

[crioten]

i just joined, and its my first post, so be nice

ive been doing a little research on raising the power of my two door '77 chrysler lebaron. it has the factory 318 with the 904 transmission.

currently i have:
`long tube headers (summit)
`dual exhaust (2.5" with flowmasters)
`weiand action plus dual plane intake
`MP electronic ignition conversion kit
`holley 4160 4bbl in a 600 cfm size (yes, i know its WAY to big, i didnt know about VE when i ordered it

i have a set of '302 casting heads i pulled from the junkyard, and id like to put those onto it to raise the compression a bit, being that they are of a closed chamber/heart shaped design.

when i install these heads im also going to be going with a cam/lifter/valve spring upgrade as well (one of the kits from mancini racing)

id like to rebuild the heads, so i was thinking of getting 2.02/ 1.60 valves installed at this time as well as trying my hand at porting the heads a little too.

here are my questions:

would i need to change the pushrod length at all if i decided to deck the heads further to raise the compression even more?

whats the max you can go with milling the heads without having to get new pushrods?

with the raise in compression ratio, the carb that i have should be ok right?

what mopar perf. cam should i go with on this?

thanks for the help in advance

I can't help you out with the other stuff, but about the cam. what type of drive are you going to be doing? Do you have a stall convertor or a regular convertor in the tranny? That will make a difference when choicing the right cam.

I am basiclly going for the same setup as you with the exhaust, intake, carb and ignition, except I'm building a 78 d200 with a reman long block. Are you running an electric choke or manual on your carb?

im planning on using this car as a cruiser/occasional strip car.

right now im using the factor torque converter, but i do plan on upgrading that in the future

im running a manual choke on the carb

thanks

I would go onto summit racing and take alook to see what they have for that type of driving and look at the RPM range of the cams. Thats what I did and it took me about 3 days before I finailly decided on one.
