parting out built LT1, heads/cam 355 Options

[StanIROCZ]

Thanks Alan.

How much power did this motor make? Is the tune still available if he wanted to cut and paste (not sure if there is a file that can be sent or??)?

Alan, what size cam were you running and is it available?

Are the valve seats for the rusty chambers going to need replaced?

(bro inlaw just bought a 97 SS and is interested)

Cam was an Ultradyne grind - 234/242 @ .050, it is spoken for.

I can pop a valve out and see if the seats clean up with scotchbrite

I popped the intake valve for one of the rusty cylinders out - guide is still tight, had to tap it out with a wooden mallet.

Looks terrible, eh?

But, about a minute with a scotchbrite pad cleaned the valve and seat up nicely, doesn't look like any real damage was done:

Hi Alan. I know it's not listed, but do you have happen to have the wiring that goes from the optispark to the ignition part of the wiring loom. The Dynaspark that we installed had the wiring built into the Dynaspark unit so we pitched the cable, figuring the Dynaspark was the last opti replacement we'd ever need. The one time I don't horde something and it comes back to bite me.

Jason - That is a part that needs to be replaced every couple years anyway - the opti end connector will corrode, gets a green fuzz on it.

Caspers makes a harness for the late opti with the long snout. $45 at Summit, part number CEI-108097

I used to keep one in stock, not sure if I have one now, I can check tomorrow.

373rwhp at about 6100rpm. TQ was 345 about 4000rpm The big Ultradyne cam was a little too big, or not enough displacement, it was a little soggy on the bottom end.
Tune is all here: http://www.frrax.com/rrforum/index.php?sho...c=16020&hl= it is not locked so if I could find someone to read the flash from the bare PCM the buyer of the heads can have it, but honestly, the tune will have more to do with choice of cam than anything else.

The same heads with a LT4 Hot cam had a lot more bottom end, got me 192MPH at the May 2001 Silver State, it was probably about 350rwhp then.

The original cam that DRM put in the motor when they rebuilt it was a baby smog cam, made 323rwhp with CARB legal accessories and shorty headers and a single cat. That cam later went into the Fowler #92 AI car, and was perfect there, about 330rwhp and 3200#, was right on the AI spec.

Alan, thanks for looking and thanks for the part number. Good luck with selling your chassis and mill.
