What do you think is the biggest CID that we can get out of 350 block ? This would include any changes in bore,stroke,rod,and possibly an off-ground crank! Thanks in advance for the ideas! Roger

With a 3.875 crank I calculated 395cid with a .030 bored 350. It'll make a good long track motor, but may be cost prohibitive to make last. Might wanna try a Rocket block for something like that.

i found there is not much difrence form a 383 an a 395 my friend runs both in his limited late model.only thing i have found difrent is the 395 will come apart around 7000 rpms and the 383 will stay untill about 7500rpms and these both dynoed over 600 horses and 500 ftlbs of torque,that was just cast cranks also u could always get better crank may help alot.anyways the 395 runed for 2 years in a super street car but he put in that late model an turned 7 grand an that badbot come undone lol. and thats my 2 cents anyways

At our track we run limited late models. Steel block 410 c.i. limit, holley 4412. If you run a 358c.i. you can run a 650 cfm holley 4-barrel.The only things they check is for aluminium heads,carbs,and for roller cams. I have never seen them PG for C.I. with this in mind my thoughts went to starting this post. Somebody I talked to mentioned a 402, just looking for ideas!!! ROGER
