I will admit i never read this thread or if I did was awhile ago. BLOCKED Dan since is same thing again, and AGAIN. Like an episode of I Love Lucy.
But will state I have no I'll will towards DanDaMan.
Since all threads are the same let me cover my thoughts and advice.
1) buy a car, the best one you can.
2) no matter what drive line, , and a complete tune up and proper maintenance Along with making sure current safe tires! Enjoy car
3) if a 225 see above #2
4) after car us safe and #2 completed at later date
318 can be upgraded with.
A) Exhaust. leave exhaust manifolds on add a Summit, Jegs eBay duel exhaust kit.
B) normal stock 340 intake, Performer, Offy, etc short duel plane, even a Holley Street Dom.
C) 500-600 AFB or AVS.
D) You don't have the car so. Don't worry about the upgrade on things like.
Upgrade from drum to disk. Don't worry about 904-727 to 500-518 etc, or gear venders!
Don't worry about new Cam. Don't worry about converter.
Don't worry about upgrade from 7 1/4 to 8 1/4 or 8 3/4
Don't worry about what headers long, short ect
Buy a car the best one you can instead of getting cheap and putting stuff on it. Spend the $ on a better car upfront.
Did I mention buy a good car?
And lastly the best advise.
Since you ask very basic questions on regular basis. I Please, Please for the love of God Pay someone qualified to look the car over before you buy in addition to yourself. If the last statement offends you sorry,but that will be the best money you spend period!
