What RPM are you shifting at and what RPM were you spinning through the traps? What did you mean tranny won't shift out of 2nd until almost end of 1/4 mile? You mean tranny just won't shift or you're not hitting shift RPM til then?

Matt , 4600 Rpm on both. Its the shifter itself , just a cable adjustment thats needed on the shifter or a shorter cable ( Hurst Promatic 2 )

Starfire 383, I had 4.56's in there, they would of been ok with 14-15 rim taller rubber but I'm keeping the 13's for now so I switched to 2.73's to keep the rpm under 5000 because thats all the stock valvetrain is good to. I'll still run the stock suspension since I'm not having any problems with it and never had. I do run a minispool with the stock swaybar in the rear but everything else is the way it was when it left the dealers lot. My helper said on the last pass , the front wheels almost lifted. :D Doug in Az 8)

Sounds like you had some fun at the track Doug. It's good to hear the engine is running well for you. Going by your best 60ft. and trap speed times so far, you should be able to hit about 14 flat and 100 mph pretty soon! The higher rear gears did seem to give you some really good mph with less revs too. Especially once you get that shifting thing fixed and some more track time with it. Doug, you didn't want to leave those front wheels on the ground anymore did you?!! :P That car really does have some potential when you realize the motor is mostly stock too!.......I'm pretty sure that you like driving that car at the track-and to it as well........Dean.

Dean, its a pretty mild car to drive on the street but its towed to and from the track till I get a trailer or dolly.

The Summit E.T. series starts the 26th and I'm going to get it ready for that first raceday .

I'm happy with the 2nd pass ( excellent reaction time) If I had done a better burnout, I would of been closer to 14 flat.

As for the wheels up deal , almost..........................doesnt count! :wink:

The Monzallac is wounded! :cry: ( spun rod bearing ) Overeved on 2nd time trial- stuck in second gear again.

Got my points for crossing the beams while wounded in eliminations and my fastest time to date though. (14.27 -1st time trial)

I'm down but not out ............. Bill , :)

I'll throw a crank in or a short block before the March race. The February race will be run with one of my trucks.

It seems to not want to go into 3rd gear on some occations when racing. I adjusted the shifter again last week and worked great on the first time trial and the elimination round but on the second time trial is when it didn't .

I missed the third time trial checking the oil pump ( external mounted ) for the source of the low oil pressure. I guess the pressure valve sticks sometimes on these pumps that Mellings make ,but not mine.

Thats when I heard the the rod knock........................ when some curious Mopar guys came over while I restarted it.

Caddy VS SM BLOCK CHEVY

Postby danfigg » Mon Jan 28, 2008 12:57 am

Hi Hi winding I dont want to sound like a &ick head or nothing I just want to be clear and I want everyone else to get an understanding here. You went thru alot of work to get the Caddy motor in your Monza and you went 14. 30's with those 4.56's and by putting in the 2.73's you went 14.21's. A basic 350 could duplicate the same numbers without all the hassle that you went thru. Im quite sure I know how you fell as my car went 12,50 with a professionally built 383 stroker. I could have duplicated those numbers with a stock 350 and big cam and decent heads and saved 2800.00 dollars. My friend had the same issue. He has a 69 stepside pickup with a 350. It ran like a raped Ape. Low 13.'s. He put a 70's 454 bigblock in it. As stated by the previous owner of the big block, "It was completely rebuilt top to bottom using the stock parts." Well a 225 horsepower motor rebuilt using the same parts is going to result in a rebuilt 235 ish horse power motor. Nothing more. The guy was warned to stay with the small block and not to put the bigblock motor in. Well his trip at the track resulted in a 16. 40 and no matter what he did he couldnt get it any faster. So who made out here. The guy who sold the 454 for 1800 bucks, and the guy who bought the 350 for 900 bucks and by the way the 350 was put in a 73 camaro that went 12.70's at the track. Pick your poison I have a few options I might be working on and I will share it with you guys. A 377 flattop motor and an experimental project. I am thinking of making a short rod 350 using 400small block rods 350 crank and 327 pistons. The reason for this experiment is that the Ford 347 stroker seems to be such a beast. Same stroke but a shorter rod. The experiment will also include a 7-4 swap camshaft. Fell free to comment on this---------------Danny

Dan, I like you idea of the 377. I always thought that was a a cool combo. I was thinking about putting a 302 crank in a 400, I think it figured out to be a 348. My Idea was to get the biggest piston with a short stoke. I think this would sream in a light car like a vega. :wink:

Dan ,I was looking for consistancy that the big motor has, not speed .

Look in my garage for the last 2 runs, even with a bad reaction on last Saturday, they are close. ( with a stock convertor)

Both runs were made with the 2.73 gears, the 4.56's ( from the 151 days) were only to test drive the motor around my house to make sure it ran ok " BEFORE " I took it to the track.

Yeah , I could of had a SBC for less , but I don't and I don't freaking care. :D

My motor cost is $200 included in the total to put it all together only because stuff was missing when i got it .

Look at the 1/4 table , Charlie went slower than I with a mild SBC. Mine is stock from the factory other than the overbore ! :?:

Charlie rebuilt his and it uses oil , mine has a slight rod knock . ( easy fix- I've done twice with the 151)

Enough said ?

Doug, unless you are building a car for someone else, don't listen to what they tell you to do. I think you did a nice job and the car did what you wanted it to do. Not everyone can do what you did.

Doug,
It sounds like an easy fix. Also get the shifter sorted out and I'm sure you will run the number your looking for.

Dan,

Your logic makes sense for about 90% of the people on here. It is a lot harder to do the odd ball swap and make it work than it is to throw a smallblock in there and call it a day. Innovation and fabrication of the less common swaps appeals to most of us. Doug pulled a 151 and put the caddilac in. I pulled a built 355 and dropped an LS1 in, Kevin pulled a 400 sbc and dropped in a turbo buick V6. Thats what I as well as others like to see. Not to sound like a d%*k but your 383 should run a lot faster than it does.

Good luck and enjoy the hobby.
