Thanks Jerry. Once I check what parts I have in the WAZOO inventory I'll be for sure ordering what I need from you.

Yun,

Depending on which cams you go w, I could have a calibration for you. Been helping out GC w his 380 over the last several months plus tune on my own
motor.

Just saw this.
Here is what I have discovered.

I've tested most all cam combos and have found out the exhaust does not need more them .230 duration and that's on big inch motors with big intake cams.
On a 350 more then .225 is way too much and very hard to tune it does not matter how much fuel you take out the issue is the valve is open so long that it just does not burn all the fuel basicly telling it in simple terms.

This is the reason why most have a hard time tuning with big exhaust cams.

Here are some samples.
441ci runs 10's @ 133+ .247 .470 In .229 .440 Ex (auto)
427ci runs 10's @ 134+ .242 .450 In .224 .415 Ex
441ci runs 10's @ XXX .240 .440 In .224 .415 Ex
350ci runs 11.0's @129+ .242 .450 In .224 .415 Ex

All the big inch motors make over 525 rwtq peak.

All above cars drive like stockers,drive to BG every year they run hard and drive back home aprox 1000 miles and get 25 mpg.

Pete

Maybe more tomorrow,i'm tired.

For me driveability and durability is most important. Also, trying to minimize cost. I might go with stage 1 intake cam (if I can find one at reasonable cost) but most likely keep stock exhaust cams.

Yun,
Are you doing anything with the gears or staying with stock ratio?

At least for now - staying stock. Once the motor is done, then back to front brake conversion followed by coil over conversion. Then, maybe 410 gear. We shall see.
Almost forgot! Two more front speakers in the doors.
