340 t/a rebuild

[acr mopar]

Hello  l am looking to rebuild my aar t/a block and wondering if anyone could give me some feed back on seal power as a rebuild kit.
l noticed they offer complete master rebuild  kits from  Rock Auto.

Sealed Power makes good parts , & Rock Auto will have good service & pricing , don't forget the 5% discount code

Hi Chryco l was told if l decided to use forged pistons they tend to be a little noisier. Is this true ?

yeah if you can hear them at all over exhaust cam etc LOL , I would only use a forged piston , for the $200 you save running a weaker cast or hyper piston the gaskets will cost more

[Mopar Mitch]

Forged pistons are always the strongest... hyper-utectics are still cast.  You want to be assure yourself with some protection from detonation/pre-ignition by favoring forged pistons (in performance applications). When the options exist, go with forged pistons.

[Cuda Cody]

Go with Forged.  Cast has some advantages in newer cars with computers to control the detonation as they do not change size as much with heat and can have tighter tolerances.  But Forged is going to handle any trouble YOU might have much better.

4032 forged is my preference, unless your going for huge boost numbers or ridiculous amounts of NOS, then the 2018 alloy would be a better bet.

I have move forward with my rebuild  :burnout:and looking for some feed back on this comp cam crs xe274h-10  ADV Dur  274 INT 286 EXH  Valve Lift 488 .491 gone with 2316 spd pistons standard heads 202 and 160 4 speed car with 391 gears six pack carbs. I am swapping out the 391 gears for 323 I prefer the highway cruiser .

This would give you less duration & make it more drivable with more lift to boot http://www.lunatipower.com/Product.aspx?id=1545&gid=287

[acr mopar]

This comp cam has duration @050 lift is 230 int 236 exhaust. Buy the sounds of things  this comp cam is a little to much cam for what I am looking for not looking for the mustangs and Camaros. just a highway cruiser. The passion 5 speed 833 just not in my budget .

Thanks again
