was wondering if anybody has run one before with any luck. and what all would need to be machined i have an old 305 i pulled the bottom end out of and found a 400 in a junker. run a 360 cid 9:1 comperssion rule so i figured i could just sell the 400 block since i have no use for it

keep the 400 block and use a short stroke, long rod combo to get your 360 CI.

i agree, the shorter stroke and longer rod will work much better than a stroked 305.

thanks but if i had 1000's of $ to throw into a motor i would be in the class that i could just use the 400 in i'm just tring to put a back up together out of the parts i have.it's not very cost effective to build something like that when you have a $200 claim and race for 90 to win weekly. what would you have to use to get 360 with a 400 block?

well my 2 cents lol u can take the 400 block and a 327 crank and i think that makes a 348cid i know a 350 crank in the 400 block makes a 377cid thats my to cents DRIVE FAST BUT ALWAYS TURN LEFT

can you put the power on the ground I'm assuming you run narow tires sometimes less is better I have a friend that runs a 4.3 and does well he never spins but of course all tracks have diff rules

yes i do run little tires 205/70 or 75 depending on the track i'm used to running runt motors anyway the first two years i ran a bone stock 307 had about 100,000 miles on it just put a cam in her and went good little motor on dry slick and sloppy but if it was tacky i would be left in the dust

Do the tracks slick up as a rule up there I would have thought they would stay together pretty well

it depends aot on the weather and how lazy the track guys want to be on a hot windy day it will cap off real fast. another thing with this black dirt is you can't get it to wet or you start haveing troubles with ruts. you'll never know what you'll get one week it will got real hard and lay down rubber before the nite is thru and the next nite you'll have to tie your shoes real tight if you plan on walking around the track or it will be dusty and crumble untill the sun goes down then the moisture come back up alot of our trouble is they need to bring in a bunch more dirt it's got such a hi rubber mix in it now it's hard to keep it right

i'd still go with the big bore, short stroke, long rod combo every time. you can turn a lot of rpm's with this deal and you can gear the car to run on any surface. a driver with a sensitive foot can get away with a taller gear and go faster. a lead foot driver will need a lower gear so when he busts the tires loose he can let off and hook it back up quicker. i'm not stating this as fact.....just my opinion.

Kieth Black makes a piston for this square (3.76 x 3.75) combo, #kb 145.

don't know that I'd run it, but .....

It uses the 400 rods and crank (crank mains must be turned down from 2.65 to 2.45"). Comes out to 334 ci and 9.2:1 with a 64cc head.

Got a friend who runs a roller 334 in his IMCA mod, hard to beat on dry-slick, fast on tacky too!
