To make a long story short, I bought an unfinished project car from a young kid, that has turned into a nightmare. Basically I have an overheating motor with barely any oil pressure.
Here's what I have in it right now.
D1VE 429 block that I found chunks of hardened permatex going down the lifter valley return holes and a head gasket on backwards.
D0OE-R heads that have been decked an unknown amount
Pistons that were supposed to be 11:1 but turned out to be the low compression variety with the bath-tub size valve recess
Weiand stealth intake w/speed demon 750 also 2 stage nitrous set-up.
CompCam 270/280 dur .519/.520 lift.
MSD 6AL
MSD 8580 dizzy that had light silver springs and red bushing. Now it has heavy silvers with the black bushing. 14* intial timing 32* total timing
I'm tired of trying to guess whats wrong with my oil press. so I'm going to pull the motor and find out what's going on in there. Going to do the block oil mods, put a new hi-volume FRPP oil pump in and mic all the journals and bearing bores.
If the cylinders check OK, I would like to replace the pistons with KB hyper flat-tops with -2.5cc. This should get me somewhere around 12:1 CR, won't know for sure until I cc the heads and see where the pistons are in the bore at TDC.
I would also like to convert the carb over to E-85 to compensate for the increase in CR.
My biggest indecision comes in cam selection. Would a hyd. in the .600 lift and 280-300 dur range work for this,since I would be using a 100-150 total shot of nitrous, or would I end up being under carb'd?
Car will be mostly street driven with a few trips to the track thrown in now and again.
What do you guys think? I value everyones opinion on here.
