Slapped some new heads on the SLO. P&P, 1mm over sized valves, shaved .004". WHat type of HP gains can I expect? They flow pretty decent stock but I’m sure the stock exahust manifolds will be choking it off now. Needs to be opened with a good set of long tubes (in the werkz). I’m hoping for 15 wheel form the heads. Another 10 with the long tubes. Sound about right?

I’m thinking no matter what you’re going down to the other 3.2 mtx in the area…👋

I think it will be hard to say what to expect…it’s possible the intake side of the combo may become a restriction as much as the stock exhaust manifolds. Whatever the case I’d like to see how the car responds to the new heads and a set of long tubes.
Reminds me of a time a few years back with the Mustang. I was running a pretty complete aluminum head and cam combo but still had a ported stock intake manifold. Had a ton of torque but fell flat on it’s face in the upper rpm. Could only trap 98mph with this intake!!! Swapped to an Edelbrock upper and picked up 10mph (no joke)!!! Who knows if the SHO will be a similar situation???

Stock 3.2 short block = ~ $400
Stage II cams = ~ $650
P&P intake plenum and runners = free but A LOT of time
BBB’s = ~$200
Pro-M 77mm MAF = ~ $250
UDP’s = $250
SS y-pipe (which is currently missing :snky: ) $ 400
30lB Injectors = $200
Ted B LPM = $200
Walbro 155 l/hr fuel pump = $80
My new heads = ~$1500
You could probably pick up most of this stuff cheaper then what I paid for them, via E-bay or SHO classifieds.

After looking over your list I forgot about some of your supporting hardware (butterflies, p&p manifold, injectors, etc.)…therefore I think your estimate of 15hp for the heads sounds reasonable. What happened to you SS y-pipe???🤣

Hey nothing wrong with making 2 sets of custom 1.75" SHO long tubes

Or 3…depending on price and availability. What is done as far as the y-pipe???

Not much Ron’s SHO will be the test bed for the long tubes

It would be custom, probably connect further back then current y-pipe and require a chop of the cat back…
Or a dump 😉
Looking at about 35" in length.
