Falconer Heads with Ti Valves assembled and also my build

coinage · Post by **coinage** » Wed Oct 04, 2006 10:27 pm

i bought a set of heads and valves off of will a while back, well i got them back from the machine shop today and thought id post some pics up

Falconer race heads-ported
Ti valves w/ 5 angle valve job
crane springs, retainers, locks
intake + exhaust seals
1.6 summit full roller rockers

I guess ill just post everything here..

these heads are going on my 3400 block with stock internals.. we(me and my brother ((eric/coinball))) are still undecided if we are going DIS or a dist setup. it will be turbo'd anlong with custom headers/ y-pipe. not sure what else to put, but i guess i can update whenever..

some of the basics
-86GT 4sp w/ custom rear 88 suspension
-3400 w/ 2.8 topend
-Garrett Ball Bearing T3/60-1
http://www.atpturbo.com/Merchant2/merch ... y_Code=GTB
-custom A/W IC
-Quartermaster twin disk racing clutch and flywheel
-4pt. cage by Doug Chase
-42lb/hr injectors

some other goodies
-APEXI AVC-r boost controller
-Zeitronix WB with boost and EGT sensors
prob other stuff im forgetting about

Now the 20k dollar question is, Did you ask your machinist to weigh a stock valve vs the TI one so we know how much less it is?

They look good. Can't wait till you get that project done. Its going to rip.

They look awsome.

OMG i'm going to cry if I don't get a set of these!
That looks awesome
Mind handing over the part numbers of the equipment that you used to rebuild it with?

Shaun, look up the material properties of ti and steel, and you can get a good idea of how much weight is saved, since both valves are the same dimensions. You just have to weigh a set of stock alves to see how much is there.

In case he didnt weigh them.

Couldn't agree more. Those heads are fantastic.

I noticed from those pictires that those heads don't have the "shark fins" in the intake openings. I'll be curious to see the dyno figures on this build. Some people say that removing the fins will cost you horsepower. My heads don't have them neither. Here is an old picture of mine.

actually you can see it in this pic http://img214.imageshack.us/img214/9975 ... tedef9.jpg

but its ground down in side.. doesn;t need to be as big as stock - knife edging it and shrinkingit some is good for flow

sorry guys didnt have my machine guy weigh them.

Chris-Nelson- i am at class right now but i can get you the #'s tonight

You need to get some polycarbonate valve covers (bulletproof glass) to show those sexy rockers off.

I LOVE clear covers like that. I was/am seriously contemplating using a plexiglass cover on my ITBs, so you can see the throttle plates and the fuel spraying in and such.

HOw long does it take before they get all yellowed up and gross from oil and heat?

Show cars don't get hot :la:

p8ntman442 · Post by **p8ntman442** » Thu Oct 05, 2006 6:23 pm

just have an alluminum insert to use 95% of the time, and use the clear for show. They will be full of oil vapor when running after a little while.

Then build a full scale plastic model engine and push the bitch off the trailer when you get to your shows.

It'd dyno about the same as what you're gonna build anyway.
