If I buy a long block or short block, like a ZZ4, Fast Burn, or 350 H.O. and H.O. Deluxe, can I install the TPI setup as long as I have everything necessarry? (i.e computer, wiring harness, sensors, etc) And if I wanted to buy a long block or short block which ones would be compatiable with most of the parts and accessories off the L98? (i.e. water pump, damper, flexplate/flywheel, distributor, starter, etc)

 

Yes I think that all those motors will work EXCEPT I know one ofthem has VORTEC heads on it so that one wont work...I wanna say its the zz4 but I'm not sure....look into it..

I believe the ZZ4 has the aluminium vette heads on it. Casting 041 I think.

And I think the Fast Burn heads are Vortecs. NO gaurentee's on ANY of the information.

 

The ZZ4,350HO, and HO deluxe Longblock have vortec heads, if I'm not mistaken, and an intake manifold set up for a carb. If you wanna transfer stuff from a L98 to a newer block, get a L98, L31 or ZZ4 shortblock.
You can get any of the above mentioned longblocks but you would have to use a Scoggin-Dickey Vortec-TPI intake base($400).

 

they are the 113 casteings ..... the fastburn heads are aluminum vortecs ( 713)




PONTIMANIAC 90 ..... The " H.O " 350 uses Vortecs ....the ZZ4 does not ....



(the ZZ4 is a 4 bolt main ...and the L98 is a 2 bolt ....but I don't know what the L31 is

 

I bought a ZZ4 shortblock so I'm not sure what heads the longblock ZZ4 comes with. I do recal that they would not mate to a TPI intake so they might as well be Vortec as far as I was concerned.
L31 is a 4 bolt version of L98.

......also both L98 and L31 differ from ZZ4 by the fact that ZZ4 has forged crank and rods as well as higher comp. ratio.

 

The ZZ4 comes with the aluminum 113 vette heads ( 58 cc) .....they came STOCK on corvettes with TPI ....... so if they were the heads that were on it ..... then they should fit . The H.O version .....came with the vortecs ..... they WON't bolt up to your TPI . Then there is the Fastburn 385 ..... it came with aluminum vortec heads , they WON't bolt up to the TPI either.


IF it is a ZZ4 ....the TPI will bolt on.

also the ZZ4 has PM rods ( forged ? ) and an undercut rolled fillet crankshaft ( forged ??? ) .


hope this info helps a little

 

So, old school bolt pattern or good old Centerbolt heads? TPI came with both depending on year, does the ZZ4? Might be y his TPI didnt bolt onto his ZZ4 crate motor.

(i.e. water pump, damper, distributor, starter, etc) will bolt up.

flexplate/flywheel, depends on the block, I had to get a diferent Flywheel for my old 1969 4-Bolt block.

 

well probably because they changed to a one oiece rear seal in 87 right .....thats why you needed a different flywheel .....different bolt pattern right ?


so....you are saying that a 86 baseplate ....is different than an 89 ? Didn't know that ........

No ....the ZZ4 heads are ZZ4 heads they are centerbolt style . I don't see why this would matter ....but I am sure someone will tell me LOL


so what years of baseplates will not bolt up to this then Hawk

 

I think you guys are confusing some things about bolting up or not...

Fastburns and Vortecs have raised intake ports, so even if you *could* bolt then to a non-Vortec style base(as comes with our TPI cars) the ntake ports are such a mismatch, vacuum leaks would be ineveitable...without some major cutting, welding etc...all said and done, still would be inadequate for the heads.

Sooo, you need to run the Scoggin Dickey baseplate for Vortecs....maybe someone else makes one now, not sure...
Differences in the '87+ vs pre-87 intakes is the center 4 bolt holes are at different angle, many have elongated the holes to work for either. Infact my Accel base plate works on both...directly from Accel...I'm sure the other manuafctures of aftermarket baseplates are the same, but I've no direct knowledge.

 

My edlebrock has the 2 angles on the bolt holes aswell ..... I know the vortecs don't line up ......... but the ZZ4 heads aren't Vortec ........ I think the guy was wondering why his stock tpi won't bolt up to the ZZ4 heads ........... and you answered that too .......... the stock baseplate ..... needs the holes changed ( doesn't seem like a big deal )



But my next question is ............. if the ZZ4 heads ( 113 " vette" heads) won't bolt up to your intake i guess the intake was
pre-87 ????

 

That would mean he has a '87+ intake...the Vette heads used the older (pre-87) pattern for all years, IIRC.

So he could modify what he has, or go aftermarket...probably preferred anyways

 

SO ........ those heads on the ZZ4 ( centerboltstyle ) are at a different angle than the other centerbolt style heads ????????


NOW I AM REALLLY CONFUSED

 

Yep, keep in mind this is info I know only from this site, not firsthand, but believe it to be reliable from those who have had them (113's).

 

WOW , Well you learn something new everyday


thanx Thirdgen.org

 

Got your question answered there I see. And yes the Edelbrock intake u got mounts both.

 

My bad. I should have looked at the same website I gave a link to. I guess, I forgot. I bought my ZZ4 shortblock a couple of years back. I remember that I was gonna bolt up all my TPI stuff to a new 350. The "350H.O." would not do, because there was no TPI/Vortec base, at that time(or headers for 3rdGens). ZZ4 came with heads, cam and intake manifold that I didn't want, for that perticular amount of money....
....so, in a sense, you are right and I am not wrong, from a certain point of view.
