Stay with the stock crank it can handle well over 400 hp, get a nice set of new rods, I would go with bigger heads for that cam also

I know a lot of guys use them but I would drop the speed pro's and go with a probe 12334 piston or something better.

What’s wrong with the speed pro’s?

^ That would be one of the better ones. I know the probe pistons are a lot lighter than the speed pro's; even lighter than the stock pistons, this will take more stress off of the rotating assembly and rev faster. The ring size will also make a difference, for what you are looking to do I would run pistons with 1/6, 1/6, 3/16 rings.

I looked @ the probe pistons on summit and they dont have them in stock, i dont have alot of time and need to get everything this week.

CP pistons should be available off the shelf. Im beginning to hate these budget builds.

These come directly from probe in CA; they shipped mine out the day after I ordered them. Summit does not stock pistons until they get a large order for that piston; at least that is what one of their sales associates told me.

pistons you are looking for. 4cc valve relief and proper ring size. I have em in my 355.

would these work?

^ Yes I think they will, I think they are just higher compression than the 12334 pistons; you can run a thicker head gasket to get your compression where you want it

I have those speed pro pistons in my forged 355.. They work awesome!

No problem those are the ones I am running with le1 heads and victor reinz 5898 head gasket; it ran really strong with a bad opti, I am anxious to see how it runs with my new ignition system.

what #'s did you put down, with this being my first build and when it came to the pistons i had no idea on.

henry172

I never got a chance to dyno it I literally put it together then drove it around the block and the opti took a crap. I had a slight miss and after the first time I went 3/4 throttle the car began to really run like crap, then no more spark. I can tell you with the hotcam only and bad rings it made 300rwhp; the new motor with the le1 heads and hot cam felt a lot more powerful, it was night and day difference. If I were to take a guess I would say somewhere around 370rwhp maybe more; I don't see you having a problem making 400 to the tires with a much larger cam than I have. Be sure to have your rotating assembly balanced.

thats would be some good #'s out of the hot cam, I will have the rotating assembly balanced for sure.
