[714x4lover]

i just put a 383 stroker motor im my 71 chevy 3/4 ton 4x4 longbed it weighs 5600 lbs i wish it could have more power than it has but it moves the truck like you wouldnt believe i think a set of camel hump heads, maybe another 50 or so hp, i have right around 400hp and 425 torque i had done to mine 350 4 bolt main, bored 30 over stock heads with port and polish job, chrome moly rings, high output oilpump,iski cam better than rv cam, i also i used 5.7"connecting rods, edelbrock rpm intake,edelbrock 750cfm carb, heads have stainless valves,heavy duty springs, i've also done the exhaust i used 2 1/4" pipes with dual flowmasters, if you use any bigger pipe than 2 1/2" you'll lose alot of torque i also used block hugger headers, im not really impressed w/ the headers i might go back w/ stock exhaust manifolds, but then again the stockmanifolds passinger side likes to break while your 4 wheeling so i thing ill stay w/some sort of headers any ways you can do to you engine you have now might save u a few bucks now but you'll have to take the motor out to work on it . you can put in a good cam, a set of heads is where you 'll get your most power(a good set is 202 chambered w/ some kind of roller rockers, if you get a high lift cam dont forget the hd head springs) a dual exhaust systemw/ a muffler that has good flow, no bigger than 2 1/2" pipes,headers wont hurt you will get arount 13 to 15 more hp every horse counts right. you can also put a hei distributor w/ high output moudule,coil and advanced curve and spring set msd has a good setup,or you can buy the whole distributor for 275, buying the extra componants is cheaper way to go. intake and carb holley or edelbrock works well, dont forget a good aircleaner k&n has one you can clean and reuse. oh a good double roller timing chain.
