I used to run one ,there is a boss on the back you can drill and tap for one.It really needs a baffle for it,or just use a valve cover.I run a vacuum pump currently.
It is a nice part,best thing is you don't have to worry about bending it.I had to trim mine a little more because the heads were milled and shortblock decked.

Easy tech on testntune nights.There are usually quite a few newer cars especially the Mopars running in the 10's.I do have a SFI balancer,flexplate,proper lugs on the axles.I've been torn between putting a rollbar in this one or find another roller that is setup.

Engine looks great, you are almost there!

[71 Goatman]

Thanks take man I am going to pick one up, like the idea of not bending, looks great too!

If TA Man went to 3.42 gears, he might be able to run 10.50s. Now that's haulin'. He may do it anyways with the 3.08s.

The last couple years I thought I had to gear up and up the stall to 3800 to 4200 to get into the 10's.

What many don't realize there is a bit of a trick to my setup,my th 350 has a 2.75 low gear set..So if one does the math my th 350 and 3.08 gears has the same effective first gear ratio as a th 400 and a 3.42 gear.

Hopefully all the changes are positive for my milder gear/convertor combo.

More head flow with small port volume
More intake flow with small runners
More compression from 10.1/10.2? to 10.75
More valve lift
Lighter valvetrain,
Near perfect port match,
Lighter rotating assembly ,pistons weigh 420grams,pins 109,(compare to 800grams plus for TRW's and pins)
Zero decked block
Shortblock hard blocked to bottom of water pump

What octane gas did you use before? Do you think you will to step up octane number now?

Did you get new heads? I assumed you sent yours back to be touched up.

Always ran well on 87....no issues..I plan on running 91 octane in it..Track days add some 94..

Same heads from 2009.Dave did the 305 CNC port program on them,cut them to 79 cc's,new springs,retainers,keepers,cups valve seals.Dave also did some minor work on the intake opened it up slightly to match the heads..The head/intake mating surfaces were also milled to fit.

[leeklm]

With the same cam/heads my car runs well with 91 octane , never tried anything less. However, when running less than 93 Octane from the local BP station, I do experience engine run on or diesleing. Base timing is 12 degrees at idle, so not entirely sure what is up with that... 93 takes care of it, so have not pursued any other remedies.

What is your compression ratio?

[leeklm]

Doing the math, it comes out to 10.5 if I recall correctly.

New build is alive,just did a quick fire up..scared the dogs in the house the wife thought it was thunder!Fired up quick!Test drive tomorrow!

[PAUL K]

Good luck!

Low gear set th350 now it makes sense to me.

who did the port work? I'm always fascinated at how you get more head flow with a small ports. Any tricks you can share?

Good luck on your next outing.

[Steve C.]

For interest I'd be interested in the runner volume myself. My notes on another build suggest a set of Dave's 310 cfm KRE heads were about 204 cc's. Maybe not typical but my set of Edelbrock heads ported to 313 cfm at .600" were about 227 cc's.

Steve,I don't have the exact port volume but I can ask Dave.I believe they are in the 204/205 cc range.This will give you an idea,the intake gasket used is a SCE 128103 which is 1.125 x 2.275.

All head port work was done by Dave Bisschop at SD Performance using his 305 CNC program.Dave also opened up the intake manifold for a perfect match,as well as milling the heads to raise compression. He also milled the intake side of the head and the intake itself for a perfect fit. Initial plenum and port work of my Torker 2 was performed by Derek Stewart last year.

[Steve C.]

Next time you have the intake off double check that gasket port height. Despite what the catalog states I have found the SCE 128103 intake to be about 2.320" tall. I've pointed that out to SCE on at least two occasions. The last time the fellow pulled one off the shelf and measured it while on the phone and agreed.
