Hello all and thank you for all of your great info. I have been glued to the site. I need help with rebuild.

Long story, short. I was told the engine was a ZZ4, ordered a comp custom grind hydraulic roller ( 236/242, .484/.501 lift,109 LSA), tore down the engine only to find it a -87-95 4 bolt - hydraulic flat or roller - 1-piece rear seal with the FLAT TAP setup. I pulled one lifter out and said "damn", it has the flat tappet lifters.

It has 14093638 block, 14101128 L98 heads, rpm Air-Gap intake manifold (7501), 750 barry grant carb, richmond 5-speed, 3:55 gears, 28" tall tires...

I was wanting a more aggressive cam, power and sound, but ran into it deep once I started to dig. My options now are to:

1. sell the custom grind, re-order a similar grind and replace the valve springs with LT4's, new pushrods, re-assemble and call it good.

2. keep the roller cam, retro-fit roller lifters, cam button, cam gear, chain, spider tray or lifter bars, new springs, pushrods,

3. sell the L98 heads, get new heads, new cam,...????

Im needed your opinion, Im stuck and need direction!!!

Your choice. I would keep the block if it's a 4 bolt. If your running a carb., why the L98 heads? There are far better ones out there. Don't see any reason why this block wouldn't accept a roller cam.
From the pictures it looks like one piston is different from the others???
Really depends on how much you want to spend. With the Nova you don't "need" a lot of HP to be fun.
