Hi Everyone it has been a while but finally got down to tearing the engine down. One of the bearings on the crankshaft went it didnt really look that bad but it was enough. It did spin the crank so eventually I did manage to track one down from a guy and it is tagged from the garage polished and didnt need turning instead of taking in the old one into a shop. I recently got new bearings and a gasket kit and was hoping to get to this going finally. I live in Canada and was just too freeking cold to work in the garage in the winter.
I was hoping for some help with engine combination. The cast # on the block is 53003921 from 89'-92' and everywhere I check it lists it as roller tappets but it has hydraulic flat tappets. It is a standard 4" bore and has the 308 swirl port type heads also with standard valves and from what I've read are very good heads. The pistons are dished factory pistons. I have the edelbrock performer RPM intake with recommended 7177 camshaft and the recommended double roller chain too, also competition cams connecting rods.
I was hoping to get some opinions from someone who is much more knowledgable than me. Maybe as to what the compression ratio might be and should I shave the heads, should I increase the valve sizes, switch to flat top pistons, or if the current combination should produce a good amount of horsepower. I do drive the car allot and am not looking to build a race car just want some tire burning fun (im sure everyone here can relate to
). The block and pistons seem to be in good condition it was the just the crank that caused me the headaches. I can spend some money on it but do you think the current upgrades are sufficent.
Thanks again to eveyone in advance. I always get great advice here.
