BUILD THREAD 78 Malibu 350 rocket build kind of

[olds307 and 403]

Final update. I drove the car to work yesterday after getting everything into somewhat decent shape. I'll drive it around and it misses unless you're above half throttle and it if I jack the passenger side of the car up. It runs normal.

its got be a carb issue I checked the fuel lines I don't see no kinks or anything. At this point I'm just going to throw this Edelbrock in the garbage and go get like a Holley 600 or something.

Consider a 625 cfm Street Demon, if you want brand new.

I figured out what it was. I had to go from a .100 jet to a .107 with 70x47 rods to compensate for the spacer and then it was just a little bit over advanced on the timing.

I don't have timing marks anymore so I had to go by ear which sucks but it worked.

I'm having a bit of a problem with overheating. I noticed that it slowly overheats not quickly but a "slow burn" and it will maintain the temp heated up to when cruising. My electric fans are working so that's not it. I was thinking it's the way I have the heater hoses routed from the water pump.

Theres 2 ports on the water pump one is a bypass and the other is a heater port I think. I have the 3/4 hose hooked into the water pump and I noticed it was heating up instead of the one coming from the intake. I thought I was supposed to be vice versa but I'm not sure. Im sure it don't help trying to run the heater core backwards.

So any thermodynamics wizards out there have any clue cause I'm kind of stumped. I'm going to try and hook into the radiator port.

Well decided to change out the radiator for the s10 one I had lying around. No change really it still overheats very slowly. I'm sure it's something simple I'm missing. I don't think the motor is clogged.

Oh yeah I forgot to mention that it will hover around 210 unless I give it some gas or I'm going up a hill.
