Yes, Ive posted about it somewhere around here. And I just happened to have the magazine where I first saw it on the shelf next to me. November 1995 Chevy truckin page 11.
3.00 stroke crank
3.73"...
That 3" stroke crank and its 5.94" rods can be dropped into a 350 block with 4" bore 350 pistons to make a 302 sbc. RPO L99 was rated at 200hp@5000rpm/240lb/ft torque@2400rpm.
It uses the same cam...

Nice vid, do you have any driving vids? I like the acceleration vids when it was naturally aspirated. Gearing makes all the difference with these types of builds, both for durability, drivebility,...
It could be because of the trans difference, but I think its probably moreso your cam. It was worth a tenth to avoid TCC lockup in the 1/4 mile, but I had the stock cam. It just didn't have enough...
It is the ECM that's locking the TCC at WOT at 74mph in third gear, all 4l60es do this. The 4l80es usually lock in 2nd gear at WOT.

Compared to stock, keeping the TCC from locking at WOT was worth a full tenth in the 1/4 mile on a stock longblock L31 with 4.10 gears with a 28" tire trapping at about 4900rpm, 4000lb truck.. The...
50-60hp gain at redline.
Whats your redline set at?

I would keep the Bank 1 Senor 1 and Bank 2 Sensor 1 aka precat O2 sensors as you wont be able to run in closed loop without them.

You will need the VDF for whichever calibration file you want to start with.
I'm assuming that you want to keep the stock distributer and 4x reluctor, so I'd direct you towards the stock 2001-2002...
2 way controls are better known as Bi-Directional control. Since the engine, trans and Antilock Braking System(ABS) are controlled by the same controller, its called a VCM(Vehicle Control Module). ...
I didn't suggest that disabling Adaptive Shifts was the same as TM
You recommended zeroing out the Shift Times, I'm assuming for diagnostics, and was attempting to follow your logic, which makes...
Is it an actual flare, which is where the engine rpm increase during the shift, above the rpm at which the shift was initiated?
or
Is it a shift "bog", rpm drops properly during the shift, but the...
Tunercat Vehicle Definition Files(VDFs) are not VIN locked, so if you got a VDF for the 1996-97 Vortec trucks, for $79.95 you could literally tune every single 96-97 truck in existence. With EFILive...
Glad she fired, here is the actual marine part number for future reference
$94
8M0011986 SENSOR ASSEMBLY, Cam Position
These CKP sensors are very sensitive to install, I have found that...
My marine guy got back to me and here is a 502 marine engine with part numbers and prices. ...
Make sure the O2 sensors aren't swapped or the injector banks aren't swapped.
As soon as you touch the throttle whats happens?
On my 87 blackbox when I had the injector or O2 sensor banks mixed...
I just talked to my marine guy and says that only the Marine engines use the CKP sensor, he also says that MEFI 1-5 uses the CKP sensor in marine apps.
What was throwing me off was the Ramjet 502...
As of 2004, only OEM applications had the CKP signal inputs.
Here is a GM ditty for Model Year (MY) 2004....
Ramjet 502's (502hp/567lb/ft torque)and Ramjet ZL1 454 510hp/493lb/ft don't use CranKshaft position sensors(CKP sensors)
They do use:
Ignition Control (IC) module
Engine Coolant Temperature...
Tunercat works with cal. files, Jet works with jcl files and both work with bin files

Why not get a hold of the owner of Tunercats? John has excellent service.
I'm still using my old school IBM for my Vortec tuning needs. It even has a serial port.

I'd give a set of L30 305 heads a try, they have a 58cc chamber IIRC.
L31 is rated at 255hp@4600rpm/330lb/ft torque@2800rpm
L30 is rated at 230hp@4600rpm/285lb/ft torque@2800rpm
Both engines...
Thanks Fast, much appreciated.
