225 slant rebuild for more power
The motor is in the bed of my truck gonna take it to a machine shop after Christmas. I want to run a different cam so I’m looking for stronger valve train anybody have a link to a good kit to use and any recommendations for a more torquey cam. Going to deck the block shave the heads but run same piston assembly with new rings. I’m debating whether to go 4 or 2 barrel as well. Machine shop said $1k for complete job with a fresh Chrysler red paint job. But will need to give them the cam and valves everything else is included.
The condition of the bores will tell you (actually your machinist) whether you can keep your pistons or not. If the bores are excessively worn or scored, you will need an overbore to clean up. If you are lucky you may be able to get away with just honing, new rings, bearings.
Look up Oregon Cam Grinders and either send them an email or call them directly. You give them your details on what you have, gear rario, transmission, how you are going to use the car, etc. and they will recommend a couple grinds. Don't go crazy on the cam, too easy to go wild and kill the driveabilty of the car. For about $100 you send them your stock cam and they regrind it to gain power/torque. It will require new lifters (which they have) and probably a valve spring upgrade. Stock 318 or 340 springs are an upgrade over the weaker slant springs. Again, no need to go wild, a stiffer spring requires more engine power to open them and too stiff isn't necessary on your low rpm engine.
Being a young guy and all, you might go to Amazon and look up and buy the book written by Doug Dutra. (Doctor Dodge) He pretty much took all his knowledge and wrote THE book on slants. (SlantSixDan) is one of the contributors. I don't think Doc put all his speed secrets into the book as very little content is actually devoted to racing.
I would recommend concentrating on getting a good, solid, reliable engine in the car and drive it for awhile. It will tell you if anything is lacking. Don't be surprised if just driving around in that car is cool enough for you.
