Last time out we ran 15w 40 rotella t oil with a cheapy fram filter. Between the 2 oils there wasn't a dramatic oil pressure change but there was a little. My question is has anyone tested the 2 oils and seen any et difference?

Lets not forget corrected altatude, humidity track prep etc............I only run thinner oils like 5w30-10w30 myself............. 72 Dart 470 n/a BB stroker street car `THUMPER`...Check me out on FB Dominic Thumper for videos and lots of carb pics......760-900-3895.....

It ran 7.50's in the 1/8 but that was with a set of 5.13 gear's because that's all we used to run! Went to a better fuel system then we had previous. Changed out all of the mechanical stuff. Water pump and fan. Took off alternator and got rid of the belt and pulley. Got a new set of plug wires that were same brand. Moroso. Got a new carburetor but same cfm as the last one which was a edelbrock aka edelbog. The new carburetor we kind of messed up in a way but still works. It's just a street serious proform. Added a aluminum 2" open spacer. Changed from 20w 50 brad penn to 15w 40 rotella t. Also took about 40-50 lbs off the car and probaly the worse mistake was a 4.30 rear end gear made the car a dog. Thinking all this stuff would make it go low 7's but ended up going 8.00.. It's really not far to blame it 100% on the rear end gear but I think it's safe to say atleast 50% of the blame could go there! We never got a good pass on it the first pass wasn't real good. Went 8.003 at 87 mph in 1/8 and 12.65 at 104 in 1/4. Also it had a 1.75 60 ft we didn't get a good burnout.. We had our acts together on the second pass we got a much better burnout and got the car staged real good and as soon as we let go off the botton the car came to a holt. One of the bolts that holds the caps for the spool assmebly decided to snap! So who knows on the first pass wether the rearend was starting to fight itself or what? All I know no matter what would do that day the car wasn't getting out of the 12's.. To high of gear. The 7.56 equals out to a ll.78 in the 1/4. Also timing could be hurting us as well especially not knowing where it is at so there could be a decent gain right there! Now that I got a timing light I can get it set correctly! I also got a new leak down tester which will be put to use here soon! I am also going to do a bunch of other checks so I'll deffiently keep everyone updated on this long journey and mystery that we will be going through to pick apart all the problems!!!

There are too few things the same to even compare. Of course, I'll be the very first to admit that I've been wrong before..... but I wouldn't worry about the oil.

I don't know what the true lift of the cam is and what the true compression is. I guess it's pretty safe to say I don't really no nothing that's in the motor for a fact. Like I said all I know is what someone told me. They also didn't tell us much either. Maybe I should wait untill I tear into the motor and put the leak down test on it and all that other stuff before I start running down through the combo because it wouldn't make a whole lot of sence anyway! So I guess as soon as I find out more deffient answers I will put pics and all the info up and we can go from there!

Before you tear into the motor on inspecting it check the total timing first, write that down Next look at each plug, keep them in order also so you can post some pictures of them on here. Last do the leak down and then the lift at the retainers with the .050 cam timing. BTW, to add onto your engine inspecting plate make sure and check both the intake and exhaust valve lift and timing, post the numbers so we can help you determine if the cam is in straight up, advanced or retarted Mr.Cab Racing and winning with Mopars since 1964.

Last year I had a 380 HP 360 crate motor in my D-50.Ran a best of 7.46 at 91 mph with 5.14 gears changed to 3.50 gears and ran a 7.60 at 90 mph. 7519607-CIMG0081.JPG (23 downloads) 1.33 60 ft,6.21 at 110.59 in the 1/8, pump gas small block,2950lbs,drag radials,mufflers and driven to track ...

It's been under several motors of ours but all 340's. Our first 340 that was way worn out only ran 7.70's 1/8 and it would only stall at 3200 rpm. Another motor who knows what it stalled to because it was a disaster and really never got to find out what anything would do! Now we are on this 340 with the w2 heads. I have personally seen 4000 on the tach on the trans brake in the driveway but it was a cold night and the car kept stalling out. We didn't get a chance to see what it stalled at when we were at the track. Every bit of 4000 that's for sure but I am thinking possibly 4200. So my point is when we changed from a 5.13 gear down to a 4.30 it really hurt performance beccause of the converter. Heck the converter isn't even right for a 5.13 gear but we could get away with it because the gears are so low!!! The lack of performance also comes from a few other things I am not trying to put the entire blame on the converter but it is deffiently one of the things on the list that isn't helping!!! I am doing a leak down test this weekend so I will know alittle more on what shape the motor is in. After that I am going to find out what lift the cam is and what it even is. Also going to get the timing all figured out and set but that will probaly end up doing that last.

The crate motor that was in it at the time was 9 to 1 comp., stock magnum heads, .501/ .513 lift hydraulic roller cam and 1 5/8 block hugger headers. The 9.5 converter foot brake stalled about 2600 rpm. 7521002-CIMG0081.JPG (19 downloads) 1.33 60 ft,6.21 at 110.59 in the 1/8, pump gas small block,2950lbs,drag radials,mufflers and driven to track ...

I would set the timing at say 34* and set the carb so its not real lean and run it for the weekend to test some other things(just checking things NOT changing anything) and see how the conv acts and if its constant... I would be checking fuel pressure going down the track (a gauge I can see) and start eliminating things... I hate seeing people just start throwing parts at a car

My 67 Barracuda HT with 915 heads that I ported, 265 @.050 with .620 lift cam, 4.30 gears and 28X10 MT slicks and a 4200 stall converter ran between 6.99 and 7.04 at 95MPH in the 1/8 Maybe you don't have enough compression. What is your 60' time? Maybe I am comparing apples to oranges if the red PU is you car. Anyway I would think that with the stall you have it should be 1.65 or less 60' if it has bite and torque.
