    Yes, both will swap on the 330.

    My 1970 Oldsmobile Cutlass S

    Also put in fresh VR1 10W30 and a Wix 51258 oil filter. The Wix Protec filter looks identical inside to the NAPA Gold 1258 filter inside. My new oil filter cutter worked way better. Some metal but less than the last oil change Those oil pressure numbers in the video are the fresh 10W30, still...

    Well this throttle body is an absolute POS. It is the reason it idling over 1000 rpm. Even with 3 return springs plus shafts don't seal tight. Plus it hits and jams on the air cleaner.

    My 1970 Oldsmobile Cutlass S

    Well, the timing was off, over advanced. Then I went too far retarded. In between just right, imagine that. Timing at 30 degrees checked with the light at idle, forgot to check rpm. I removed the IAC and taped it off, it idled down. It is pulling so much vacuum, I actually had to use hard...

    Hey guys, can you tell me what I have? Performance wise?

    It should run pretty good. I would add more stall vs stock, something like 2000 rpm plus. I say it will pull hard in the mid range. What year car, trans and rear? Drain the oil, pull the plugs. I would use dedicated high ZDDP break in oil, I used Lucas 30 weight racing oil and prelube the motor...

    My 1970 Oldsmobile Cutlass S

    Well, I think the high rpm issue is the TPS. My current POS TB has the TPS on the passenger side. The new Speedmaster TB also has it on the passenger side. Looking up the TPS and IAC, it requires a 87 Ford TPS. It turns the opposite way as the LS style TPS I am using. They also claim the mid...

    My 1970 Oldsmobile Cutlass S

    So it runs, just not right. It started, idled ridiculously high. It also cranks like the timing is over advanced. I changed a couple of things, dropped the cranking timing to 10 from 15. It wouldn't even start until I put it back. I'm going to try a couple of things Mark mentioned to try next...

    My 1970 Oldsmobile Cutlass S

    I got to the Tuning Wizard, realized two things. I want the Terminator to control the fuel pump. It can run pumps up to 15 amps or just trigger them. Key on through the Mr.Gasket fuel pump relay isn't going to cut it. I actually unplugged the relay pissing around with this. Second, I didn't know...

    Ok, so I installed the MSD Dual Sync distributor. It plugged right in, lined up #1 at 50 degrees as in the instructions, just need to check the LED for the sensor alignment. I also modified a 3 wire crank sensor plug to plug into the knock sensor plug into the Terminator X Max. The crank sensor...

    My 1970 Oldsmobile Cutlass S

    So a couple of little things. The different throttle/kickdown cable bracket arrived, should work better. Also the 10 micron fuel filter element arrived. I ordered an LS knock sensor harness for dual sensors off the block and a second sbc truck knock sensor, thinking that would plug into the...

    Race fuels

    Unfortunately limited traffic here. Yeah, alcohol is corrosive and absorbs moisture. Joining Classic Oldsmobile and posting in their high performance forum should get some answers.

    The Hyfire box and main power are wired and routed. Most stuff connected, just need to figure out final routing and where to put the ECM.

    My 1970 Oldsmobile Cutlass S

    I ordered a 10 micron element for my filter to replace the 30 micron element and different throttle and kickdown bracket with more adjustment, more solid and looks better from Amazon. I clocked my O2 sensor for the wideband and the Holley EFI at the angle Holley recommends and installed the...

    My 1970 Oldsmobile Cutlass S

    I got the new temp sensor for the Terminator, actually swapped spots with the heater hose, further down in the intake. I added the oil pressure sensor for the oil that the Terminator reads. I also ordered the 8 AN to 1/8 NPT to install the same sensor for fuel pressure just before the rail. The...

    Wiring AC relay after CCC delete.

    I believe it just needs grounded. It grounds through the ECM. The LS swap is meh to me. Their low end is embarrassing stock in trucks. I have drove many, all the same. Our 6L 3/4 ton 4x4 is useless below 3500 rpm, doesn't come alive till 4000 rpm. It can't pull the valley hills as well as the V6...

    My 1970 Oldsmobile Cutlass S

    I basically spent the weekend getting the fuel system ready for SEFI. I added the 30 micron fuel filter with EFI rated braided hose with twist together 8 AN fittings and EFI clamps at the motor. I also replaced the one small piece just behind the motor with braided hose and EFI clamps. I dropped...

    How to post pictures

    The Battens flow the best but most have been molested multiple times and were so so quality new. They haven't been made for years. Just get CNC Edelbrock's done by Bill.

    My 1970 Oldsmobile Cutlass S

    Finally the weather improved, I wasn't working in my shop in -25C highs last weekend plus my Wife was off. This weekend she is working nights, so plenty of time. First I had to address the TH350 leak. I know an old GM trans leaking, shocking. I thought it might be the pan or pump seal. Nope the...
