1970 340 has the 1973 low compression pistons
Ok guys, just looking for opinions, thanks
I have a 70 340 I bought five years ago. It was rebuilt in the 70's and sat on a stand since then. The guy replaced the pistons with 73 type low compression pistons, the ones with 4 eye brows and quite a bit below the deck.
What I'm wondering is would it be worth keeping those pistons after I check everything out with the machine shop or get the higher compression pistons? The ones in it are brand new but being a big block guy all the small block stuff is new to me and I'm on a tight budget. I would like performance since I want a it to be mainly a tough street car and will eventually run on an 1/8 mile track maybe once or twice.
I kind of feel it will be a dog with those pistons and don't want to try making up cylinder pressure with one of those whiplash type cams. The photo shows how far down in the hole the pistons are.
Here's what I have.........
*69 Barracuda FB full interior all steel
*3.55 sure grip 8 3/4 XHD leaf springs
*will be converting to a 4 speed
*255/60 15 rear tires
*X heads (stock)
