How well would this combo work?
ZZ4 short block
Fast Burn heads
Scoggin-Dickey Vortec TPI base
Some type of large tube/siamese runners
Ported Plenum
Stock?/52mm TB
How well do you guys think this setup would perform? What cam would this setup be able to handle? Possibly the HOT cam? Give me your opinions/suggestions. TIA

Re: How well would this combo work? (85z51vette)
Look at my sig. I have a similar setup. Edelbrock heads ,not fastburn, and I still have the 48mm TB. I'm gonna get the 52 soon. With the 48 mm TB, Stock chip, and no tuning, it really runs pretty strong. I have the TPIS ZZ9 cam.. Good luck w/your decision.
P.S. I don't have dyno or track numbers yet, I've got about 1700miles on it so far...

The intake system will become your bottle neck. It was designed for the 305, and even ported, will hold the motors potential back. A superram would increase flow, but retain the low end torque the long runners are famous for.
Either way, you'll need the ECM reprogrammed with your changes.

Re: How well would this combo work? (art91)
I figured that about the ECM. Just how bad do you think it be with the stock programming?
I also read in another thread on here about the Scoggin intake being made for iron vortec heads, and that some grinding may be needed to get them to match aluminum fast burns. This is it:
"The Intake has 1.75 openings to the runners and the head ports are sized for the Iron Vortec head (about the same as a fel-pro 1205 gasket) so they need a little tweaking to match the Fast Burns.
Would this be essential for proper operation or just be for more gains?

Re: How well would this combo work? (-=Jeff=-)
Jeff: I'm really gonna try and stay with the TPI setup for right now. SR may be down the road, but I wanna see/know what this will do. I think I have the free flow exhaust down, aside from stock "headers" I have the Mid America "off-road" (no cat) true dual setup and flowmasters. What are the specs on the 219? Thanks...
edit: The ecm I was suggested to upgrade to is the 7165 ecm correct?

Re: How well would this combo work? (85z51vette)
yes 86-89 is the 7165
219 specs..
LSA 112, Lift .525/525 with 1.5 rockers Duration at .050 219/219
Cool idea to try the runners.. although I would use AS&M LTRs

Re: How well would this combo work? (-=Jeff=-)
I would use:
-Upgrade to at least the 86-89 ECM
-Lingenfelter 219 Cam
-Upgrade to at least the 86-89 ECM
-Lingenfelter 219 Cam
Also, say I wanted to use 1.6RR. That brings the 219 cam to .560 .560 lift. Still recommend it? :D

I would stay away from the Fast Burn heads I talked to GM and they said that the AL Fast Burn heads were for 383 or larger. Look at the ZZ4 fast burn engine, HP went up 30 but torque dropped off by almost the same. The Iron Vortec heads will get you the same power with more torque.

Re: How well would this combo work? (mean8t)
mean8t: I don't believe a TPIS big mouth base will bolt to Vortec heads. The bolt pattern is completely different. The Scoggin-Dickey manifold is the only one I believe that is designed for Vortec heads as of now. Here is the link to it by the way: Vortec TPI Intake
What do you guys think about mean8ts comment about the Fast burns?

Re: How well would this combo work? (85z51vette)
I know that the TPIS base won't fit. I was going to tap the heads for the standard bolt pattern and port it to fit, but now I will buy the Scoggin-Dickey Intake.
