Hey there, as the few years I've been here, I've noticed alot of 305's being put into our rods. I'm writing this just to touch on the base of diff. motors and different sizes. Theres alot to pick out there folks......
Mike, who has gotten on the Jazz several times about the 305's, these motors have basically a good design. They were small, inexpensive to operate, as long as you sold them before the heads cracked. They were dependable, up to a point.
If you were given a motor and decided to hop it up some, fine. I just want folks to know you can-not build a world class hi-horse 305 without a ALOT of Parts and Alot of MONEY! IT CAN BE DONE, BUT WHY??????
You can build a 4 thats a killer, then you got the 265- 400 smallblocks, and a ton of parts out there to build destrokers and strokers, by swapping out cranks and using the correct rod lengths withthe right pistons.
On of my favorite motors to build is a old 400 cu.in. destroker that folks used to run back in the early to mid 80's sprint cars. Wolfgang in the old outlaw classes loved then along with the rest of the guys.
While there are still plenty of car parts out there for us to build, they're starting to dwendle some. Cores are starting to be used where they were not in the years past. Alot of our older salvage yars are being bought up pennies on the pound. They're starting to melt down the valued old motors and parts, as the economy tightens. Our Motors are starting to disappear right out from under us!
There was this fella from Brazil that wanted to build a 4 cylinder to go in a bucket. I say great! Did anyone see that blazinly fast pass of the 4 cyl. Mike posted? No, its not a V8, nor would I want to run against it if I had a 426 Hemi with 2x4's. It was built and it was right! A league all its own!
The money you spend for a 305 is the same, if not more than a 350. All I'm saying is look around and see if you can't find a 350......since you'll pay more for the 305 in parts, you've already paid for your sonic testing and magnafluxing of block and heads and a few other things, plus that extra 50 cu.inches is hard to beat out there on the street!
There is a consensus. Cu. Inches Rule on the street! Those cu.in.'s don't need to run to the ragged edge of explosion to unleash TONS of HORSEPOWER! You can make the same amount of power from a smallblock mouse motor all tricked out as you can from a mildly built blown big block.
That smallblock will be very temperamental and moody, chew up parts and on the verge of parts failure.
That blown big block is nowhere near being stressed out, the cars and cam will be alot tamer, and the overall health of that motor will make it live for alot of years without serious engine worries. I've seen street motors with 6-71s and 8-71s going on 10 years with over 100K on them and still going strong. And all they'll need is reringing.
Just something to think about! Turbocharging is a way to go also......and is a little less expensive mechanically....just depends on your sense of style.
As far as good motors out there.....theres old PONTIACS, BUICKS, OLDS motors out there that are just waiting to be put into buckets and the parts are cheap. These range fron 350 to 455 cu.in's!!!!! Whens the last time you was a 318 DODGE in one? The Caddys have some big inch killer motors that all they need is a cam and intake with some headers.....the bottom ends can withstand runs into the 5000-6000 range easily.
One of the nastiest motors out there was made by AMC.....worth looking into and theres a lot of speed equip. out there for the racing folks......
Just a little something to get the gray matter stirring............
