OH HECK YEAH! YEE HAH! Big thanks to everyone who gave me input on adjusting my roller rock especially member IM14! I adjusted the rockers just as he said using only 1/4 turn pre-load, fired her up, sounded the best since I bought the car, I don't know what had happened with the previous owner but he dumped all that money in that motor and the timing was way off, the carb off a little and the valves off quite a bit , surely it was running right at some point but it had been sitting up for about a year other than starting it occasionally. Anyway to the good part, I warmed her up and took her out for a drive, stuck my foot almost through the floor at about 30 mph the first time, slight cough and OMG straight to about 5500 (spinning) where it hit second, a very minimum delay and it got back on the cam and again turned em loose for a good piece but started gaining traction, at somewhere near 5700-5800 I got out of it (I was in a 35 mph zone). Dang now I'm having some fun, drove about a half mile to corner store and back a couple more times with a couple stops in a non-residential area to see if it would pull from a dead stop (remember 3.0 gears and no stall..yet) well if a bunch of teenagers would have been watching the ole man taking off they would have all been laughing and hooting at the absolute turd take off UNTIL! it got on the cam after just 10-15 yards and straight back to 5500 or so, then again slight delay until it got back on the cam and breaks loose again! As several have suggested this might be too much motor for my 16 year old...well yeah WAY TOO MUCH, what is she gonna do with 3.80's and a 3000 stall in her, I think this may have to be Dad's car and buy son a Kia or something
OH I forgot One other thing I coasted into my driveway on my last run down the street, I had put 5 gals. in her just prior to this run and had driven maybe 3 miles gently, could that thing have burned through nearly 5 gals in about 3-4 miles of hammering on it? Or do I need to look for a leak?
I bet your gonna be going to the store a lot for the wife now huh! Glad you got through that hurdle now you know what you have.
I know people joke but I dont think your car gets gallons per mile rather than miles per gallon haha, even hammering on it
hope your right I seriously don't get it, I drove it very little after putting 5 gals. in it, it was sitting on empty when I put it in there but I am absolutely positive I have not driven more than 15 miles max on that 5 gal., now I was putting my foot in it everytime I drove it especially tonight as it has never run like this, not even close. But I swear it started falling and I know it's fuel, I know that exact feeling, coasted in driveway, got out inspected "new" Mr. Gasket clear glass fuel filter and it had the hallmark empty tank as it was full of rust, not clogged either I cranked it over and it fired for a minute I jumped out and watched the fuel spitting from the fuel pump into the glass....it is MT!
unless someone else chimes in with a "yeah thats plausible" Id just go get some of that UV dye stuff they sell. I had a "slow" leak on my 300 once upon a time, just thought it was cause it was a v8 and I had my foot into it quite often, I eventually noticed a small puddle after it had been parked and by doing before and after MPG calculations, I was losing about 3 gallons a tank. Id rather not think of how much money that is over the course of a few months haha
The dead spot is either timing still a little lazy or the pump squirter on the carb is not right. What is timing set at and does it want to ping? What carb is on it? SPark
Lmao Yeah maybe I'm just excited as at first I thought I had driven only 3 miles gently then no more than 15 max but was hammering on it every time,now I'm thinking maybe it was maybe 25 miles, lol. I'm recalling my days of the 390 BB that roared from 0 to 5500 but this SBF seems to be like a mad bobcat that is just waking up at around 3000 and I'm sure will turn 7000, although thats probably pushing it as far as I should if even that.
dead spot It is very likely there is still tuning to do, I am at 14 degrees BTDC at idle and havent checked it at 3000 but Edelbrock says I should be all in at 32 degrees by then, no pinging it just acts like it's power comes on at above 2000 rpm, Edelbrock says this set up is the Performer RPM and makes it's power from 1500 to 6500 and requires 3.70 gear or lower and min 2500 stall, of which I have neither just yet........it's running so much better than it has yet and it's fast, I mean fast....so I'll be getting around to checking the advance timing and carb settings and will let ya know, Thanks again
Can't help you tune an Edelbrock. Never had one or even wanted one. Build a lot of Holleys while racing but never touched one of the Edelbrock carbs. The dead spot isn't the cam/intake, I've run a lot more cam with no dead spots in the power curve. It either wants a little more timing or the transfer circuit in the carb is lean or rich or the accelerator pump is out of adjustment. Next time you "punch it" and it bogs, look in the mirror and see if it rolls out any black smoke from the exhaust. If there is no smoke, it catches up and goes, it's lean. If it rolls a little black smoke, clears out and goes, it's rich. Might have somebody drive behind you and report what they see, and make sure it's not dust off the street or tires, you're looking for actual black smoke out of the exhaust pipes. I just don't know how to tune it out of one of those carbs, somebody here will be able to help. SPark
