Your point is well taken. Just to see if though it makes sense to use these 343 pistons, can anyone tell me what the dish volume is for the factory 343 4V and 2V pistons? I'm guessing 343 2V piston would be a better choice for me, but that's not what I have so that plan might not be workable. Without getting into boost, from what I'm hearing it seems like porting the stock heads (or maybe the Eddy heads?) along with a decent cam, 650 cfm carb and intake might make as much sense as anything. |

"Just looking for a nice performance driver, but reliable enough to drive all day at 75-80 mph in case I ever choose to drive it across the country." You only need about 150 hp to burn up tires and haul lawn chairs. One of the best combinations for a cheap, reliable 300+ hp low compression 360 engine is a simple one. Comp 268H cam Performance valve grind. Pick your flavor of aftermarket intake manifold. 650 to 750 Holley. Headers or Free Flow manifolds. 2 1/4" - 2 1/2" exhaust. Or, you could jack the compression up and burn E85. Edited by SC397 - Aug/07/2022 at 3:21pm |

LOL!
Ok, a 600 cfm with a Performer intake and 650+ cfm with a Air Gap or Torker. Or just go with EFI.

Couple of things, with the Eddy heads you can run a bit more compression.
343 2V pistons would probably be a good thing, but they are not readily available, the valve pockets on the 4V pistons run to around 5cc. I've found the deck clearance to be around 0.020" rather than the factory spec 0.012". Compression in itself might not add a lot of power, but it usually allows you to run a bigger cam to get more air in and that's where the power comes from. Nicely ported heads can do the same thing with a milder cam it seems.

Ever notice that everybody wants to race a muscle car? I just don't like getting blown away by Kias and Hyundais. I have free flow manifolds and just put a 2-1/4" dual exhaust on the car, so we're part of the way there. |

Cam, Rick is right on the money. The whole I have 400hp or I have 500hp etc is just for bragging rights at the DQ. 250-300 HONEST HP is enough for a fun cruiser. Most people never drive them to the max or don't have the skill to drive them to the max anyways. There are so many bogus HP claims by ego's in the hobby, don't fall to that mentality. My AMX is plenty quick with a basic build and is still fun to drive and bark gears. Throw a good set of gears in the back and an overdrive and it will do everything you want.
The 360 in my "cruiser" is basic also but with a Torker and highway gears. Definitely not a great combo BUT it's still fun....then again not many people try to race me. lol Took it for a decent drive through the pass yesterday and managed 15mpg which isn't too bad for a big car with a lot of wind resistance! |
