    1970 Olds Cutlass S Rat Rod Style

    Yes, a custom Qjet built by me and a Progression small cap electronic timing control distributor would have passed for stock and ran better for about $3500 less! I could have put the money into milled Procomp heads with a roller cam and had 100 more Horsepower and Torque! I am wondering if it is...

    BUILD THREAD 350 Olds engine

    As said, no gain with the Performer. The RPM the only one worth spending money on. If it needs an overhaul, Mahle makes a 10cc 1mm ring pack forged pistons in various sizes. DSS also makes a 3cc, 5cc and 12cc forged piston with a 1.5mm ring pack in various sizes.

    200r4 transmission dipstick

    They are different lengths. It will fit but won't read correctly. I bought the universal locking replacement. It needed cut vs the TH350 length.

    MCSS 200-4r questions ?

    Dr Dan Mascal builds the 2004R and he was in Florida. I believe he is now in Georgia. He was a GM tech for 25 years and has built them behind serious power. I would not buy anything from CK, took months and pretty sure they sent me a bad high performance pump. It would not shift even after...

    Anyone try the Continental Winter Contact SI Plus on any vehicle?

    Well, I pulled the pin. The way too old studded tires were replaced with the Continental Winter Contact SI Plus tires. There was some galvanic corrosion where the weights were cleaned up painted and clear coated in those spots. I also got the Schrader tire sensors, they swear by them, will get...

    Anyone try the Continental Winter Contact SI Plus on any vehicle?

    They are on clearance for a really good price in the 235/60R18 I need for my AWD Challenger. Even with adding 4 new wheel sensors, they are cheaper than studded tires on sale. Then the cost of studding and new sensors. I will check date codes, as long as I can get 5 Winters out of them before...

    SBC 350 to 200-4R

    Happens all the time. Add a couple of washers to take up most of the space.

    1970 Olds Cutlass S Rat Rod Style

    Surprised the battery disconnect still works. Unfortunately when I the oil yet again, it didn't start! The fuel pump wasn't running found the battery ground was tight and came disconnected. Still no fuel pump, could jump it. Replaced the Mr.Gasket 5 pin relay. Still no, injectors aren't turning...

    1970 Olds Cutlass S Rat Rod Style

    I went on the Holley EFI forum. I tried the AT trans tune, only had first this time. I then used the NT tune, trans works as it should now. Will see how it works this week.

    CadiRat adventures

    Good Lord, they didn't think a 500 ci engine could use more cfm? Crazy, exactly why they are malaise era cars.

    CadiRat adventures

    That should be a 800 cfm Qjet. The secondary pulloff can be removed, glad you found one. Cliff's pull offs are the best, he actually adds restriction so they don't release too quickly and cause a bog. Yeah probably the factory fuel pump. Glad the old girl is still floating along.

    1970 Olds Cutlass S Rat Rod Style

    So many hours spent and not a lot accomplished. So I started the day by marrying Cutlassefi's tune to my 4L80E. Of course the Holley files are poorly labeled. I tried the default and another, one has shift tables, the other did not. Both did a weird in and out of gear. So that marriage ended in...

    My nearly new, 0 owner 2017 Dodge Challenger GT

    Well, the Challenger is starting to show some wear and tear. I see one stitch on the outside edge of the drivers seat has let go and the 8.4 touch screen is starting to deamination on top. One is an easy fix, the other not so much.

    4L60E Conversion

    The 4L60E failed often in trucks, talking a stock 5.3 was too much for them, especially towing. There was a long standing TSB from GM, offered an affordable reman because of it. Make sure whoever builds it, does all the factory plus aftermarket upgrades for it to live.

    4L60E Conversion

    They bolt right in the same and depending on year, use the same converter. Glad you trust them behind decent power, I don't. You control lock up and shift points easier, otherwise you nothing other than a 5 pinion planet gear set on later versions. The 4L80E is a different story, much stronger.

    Oil gauge line

    A front mounted oil line like the Olds V8 requires the 5 foot line. A back mounted line on an engine, the 4 ft would easily do, if not 3 ft, depending on gauge placement.

    Oil gauge line

    Running the same on my 70S. I have a T with the braided line and a $20 Amazon vs the $200 Holley pressure sensor. The cheap sensors read about 10 psi lower compared to the mechanical gauges but hard to choke down $400 for oil and fuel pressure sensors, which I also have. Also have a mechanical...

    Best battery for a vehicles that sits for months?

    The boat battery started today multiple times but wasn't super happy even after charging it for 3 hours last night, it is going back in the boat. I installed this tonight, 750 CCA 150 RC AGM battery with a 5 year free replacement.

    1968 Olds 350 heads

    Only the W31 got bigger valves 1.995"/1.625", otherwise 1.875"/1.56" on all others. The spec is 64cc, usually 3 to 5cc bigger untouched. They do give around 9 to 1 on a 403 with stock pistons and flow much better on the exhaust side than the stock 4A heads. Olds don't have seat recession issues...

    Best battery for a vehicles that sits for months?

    Well, obviously this battery is tiny cranking amps, was at 12.8 volts last night. It starts once, not that enthusiastically. The Olds always stalls on initial start, needed boosting on the second start. One thing I noticed is the battery is charging at 14.6-14.7 volts. It only charged at high...
