what do you have If you put a 327 crank in a 350 block. I've been told I would have a 327 but would you use the 350 rods or the 327 rods and would there be any advantage to this in a race engine

you were told right same bore shorter stroke basicly you can get more r's out of it but not more power i wouldn't run anything less then a 350 unless i had no choice i'd sell any 327 or 302 stuff to street rod guys they like um and give pretty good money for it

17j, run a 331 sometime and you might say 350who...gear it deep and you might like it.i didn't think i would until i swallowed my pride and went to it from 406s'

so 7jdwmod what is a 331 and how would you gear it on a 3/8 banked track. I'm new at this and need a little advice

I built a "331" sbc. Used a 305 block and 400 crank and rods. I liked the 350 better.

cmiller,that would be like a 328....not what i'm talking about for a 331...4.030 bore (350 block) 3.250 stroke crank (327).rod lenght use a 6" or6.125" i'd use a good lower end.for 3/8 track i'd start with a 6.00 depending on momentem.i run a 6.20 and a 6.33 on a 3/8 with semi tight turns.this combo doesn't have alot of bottom end so it seems to work better the harder you twist it.

i've seen them win in late models,mods,and street stocks.i was bull headed when i started racing and didn't want anything but 400 c.i. and up in the car.2 yrs ago i decided to build a a small cube engine.first month into the season and i thought i had made a big mistake.car wouldn't come off the corners.so i threw some gear to it and won.

bryanb30,i've ran 1/4-1/2 mile tracks.you really have to gear these motors to get you off the turns.they're not much for low end power.can't lug it.as far as rods and pistons.they don't require a special piston..but..you need to get the compression up.i prefer a long rod in what ever motor i build.you can use a 5.7 rod.

the reason a 327 is so good is short stroke big bore, with the 318 block and the 360 crank, you will have small bore, long stroke so it will not rev as high.
340 with good aftermarket heads is the best choice as a mopar goes, but hard to find the stuff, if i could aford to i would get a 340 block and a forged crank and long rods, and good pistons, and aftermarket great flowing heads, and intake, nothing would beat that.
340 is the way to go in mopar.
but as far as the 318 and 360 go the best would be to leave the 360 alone or if you wanted short stroke look for a special aftermarket crank or put the 318 crank in it.

how could i do that with 318 thats all i have and i want do it cheap

318 has same stroke as 340 but a 3.91 bore compared to 4.04 bore on 340. Contact Hughes Engines they have some kickbutt combinations available and might have some ideas of whatelse you might do.
www.hughesengines.com or just search for Hughes engines. Good luck. Mopar rocks.

I've been trying to come up with a combo but haven't just yet. I'm sure you can configure something. speedomotive has a 318 to350 kit available for $795. I'll let you know if I find anything. I have a bunch of old mopar performance books I'll dig thru. Mopar isn't anymore expensive than chevy. actually you can get more bang for your buck. Sometimes it just takes a little more digging to find the right info and combinations.

Take a 318, turn down a 360 crank on the mains. Use the 360 rods. Might have to clearance the block. Pontiac 350 pistons. Get it all balanced and you have spent a little change for a decent motor. No guarantee the valve reliefs for a pontiac will work in a mopar though, but they look like it might work. What heads will you use?

If you want a small stroke motor try a 400 block with a 3.25 stroke crank. it is a 348 close enough to a 350, or bore the cly's hone for moly rings. At 4.155 (not far from a stock 4.125) it is 354 ci and it will run! Rpm is great due to stroke and it has the torque from the large bore. You must get GOOD pistons and you can run a ton of rod because you have the clearance.
We have been running these in a LOT of 355 max ci Chevy races and they are left wondering what you have. We get pumped alot!!!! We get the 2 bolt mains from guys that are getting rid of them due to overbore. We get them sleeved back to stock bore, and we have had them made to 4 bolt mains. Once the block is decked the front numbers are gone, it has two freeze plugs and we run something over the casting no's so they are hard to see. It is not illegal, it is a 350, it is just not what they had in mind. In a Stock engine combo, 500 cfm carb, stock 4bbl intake, 10:1 comp, 1.94/1.5 stock 882 heads, Log type of exhaust and mufflers with a .390/.420 278dur cam it flattens the torque curve and runs about 5hp and 20ft lb of torque over a 355. Once you start adding intakes/exhaust/better carb etc it really pulls ahead. we have seen 25-30 hp and 60 ft lb of torque, And that was still a 500cfm two bbl motor.

are the rods and pistons the same from a 350 and a 327 and just the stroke of the crank is the only difference

Bingo!Went to put 327 pistons( been a time ago) and rods in a 350 and wow what piston pop up!The top stuck out big time.Look at a 350 piston and a 327 side by side and it will be obvious.
