OK, where to start. I haven't ever gone to this extent on an engine. I've had them apart, but never to the point where I removed the pistons/crank and replaced them.
I have an 85 (84?) 360. I want to build a nice street engine that will be bracket racing on occasion. Needs to run on pump gas, the best we have around here is 91 octane. It has dished pistons that seem to be low in the block (see pics). Probably not much compression there. To get into the 12's would be nice, but not an absolute necessity if it will make it a temperamental street driver. I don't plan to use the heads that were on the engine.
My tentative plans so far. Take the block to a machine shop, get it hot tanked, check for cracks, bored (maybe .030 over?) and have them replace the cam bearings and freeze plugs, and some off the deck (not sure how much). Get the KB 107 pistons and have the shop balance out the crank with the pistons, harmonic balancer, and B&M flex plate.
I have a set of Magnum heads, but I would prefer to use LA heads. My other choices are a set of 915 iron heads with some pocket porting, all assembled with 2.02 and 1.6 valves and springs that can go up to .550 lift for $800. Don't know the flow, but they say they are good up to 400 hp.
I could get some Edelbrock heads, but I would certainly prefer not to spend that much. Maybe I should use the magnum heads. Isn't there some issues about the 1.6 rockers and too much lift for moderate cams with these heads. Also, I'm afraid I will get them to the machine shop and find they are cracked. Although, they look to be in great shape.
I have some TTI headers already. Will probably get an Edelbrock Performer RPM intake? I have a converter that is rated at 2600. That could change if needed though.
No idea what cam, but obviously depends on the compression ratio. Carb?? I prefer the Edelbrocks to the Holleys, but am open to suggestions.
I should probably get the heads before I tell the machine shop how much to deck the block? I don't know much about this. Advice is welcome.
About the harmonic balancer. Do I need a new one? It looks like the rubber is coming out of it in between. I looked at Summit, do I need an external or neutral balanced? Here is a pic of the one I took off of my engine. Should I post other pics of my block? Obviously this is a huge part of my car, and I want to do it right the first time.
