Thinking about rebuilding my L98 , maybe to 383 , or would a ZZ4 swap be easier/better ? If I do the strker 383 kit , I could use a ZZ4 cam , but would smog be a problem in Calif. ?

I wouldn't say that is shameless... you can supply what he is looking for!!! As for the question... if memory serves me some one here did the ZZ4 install and was not happy with it. I will also point out that they do have a 360hp TPI drop in crate motor!!! And it is about the same price.
To build or buy... that depends on you and your knowledge of building the motor. I was going to buy simply because of lack of time. Plus you get a warranty with it... that cant' be beat!!!
Don't have 3k I can blow right now but thanks.Still on the search for a vrigin 400 block- SFV is about 15-20 min. N.W. of LA. Napa is quite a bit further north. Beautiful up there.
i got confused! i put your "location info" with the OP - how embarrassing!
well, i'm not the sharpest knife in the drawer!
hell, i'd deliver it to napa also!
I just dropped in a ZZ4 2 mponths ago. I chose to put my stock (86) TPI back on - a few guys here in the forum told me that would choke the engine - "never see 5000 RPM" was the dirrect quote.
Well I haven't dino'ed it yet - but it is a great setup - and I routinely saw 5400RPM at the end of the straightaway during track days - BTW the 355 HP ZZ4 for some reason could hold off - and match the c-5 and c-6's down the straights- no problem (I run a Keisler T500 trans)
Sound like the ZZ4 is just the ticket ! Do all the accesories bolt up okay ? My old L98 ain't what she used to be .
All my stuff bolted right up - I just set the engines side by side on 2 engine stands (like 30 bucks at Harbor Freight) and went through and systematically changed out all of the brackets and accessories - 1 at a time - so I had a reference. Good idea to take lots of digital photos during the uninstall - it will help you lots with routing and connections later on - I just loaded them onto an old POS laptop and kept it right there in the shop - saved my bacon a few times!
From what I understand the Heads on a ZZ4 are identical to Vortek - but the Vortek are Iron - while the ZZ4 heads are aluminum carefull about torque when tightening bolts!
As for the question... if memory serves me some one here did the ZZ4 install and was not happy with it. I will also point out that they do have a 360hp TPI drop in crate motor!!! And it is about the same price.
That one has a 2 bolt main, unknown innards, and Vortech Heads which require SDPC Manifold to bolt the TPI intake up to(another $400). ZZ4 is 4 bolt main, Forged Fileted crank, PM Forged rods, and hypercrap pistons, 113 dport casting heads. TPI Intake bolts right on no problem. I think the ZZ4 is a better buy for the money. Buy the short block, drop some AFR's on it and a bigger cam and you got a nice motor.
