double check your points in the distributor. i'll bet that is your problem, if so look to upgrading to a module or replacing the distributor with an HEI style for reliablility and worry free driving. Brian

i believe the '75's were the first years without cable drive, may be wrong. my '77 has an electric tach. a newer distributor will give the ability to better tune your motor. the MSD has better advance control, adjustible mechanical advance. you can also get an adjustible vacuum canister to...

i got one from NAPA. imagine that, "no auto parts available" actually had something i needed. almost every GM vehicle from that time uses the same valve, gotta love Leggo parts. Brian

you can remove the valve completely and replace it with a spacer. then you don't have worry about it at all. the blade pins on mine rusted through and the blade fell over the opening closing off about 80% of the pipe. the spacer is like $6.00, just run the chance of breaking the three exhaust...

Rob, my bad, i was thinking of the Victor air-gap manifolds, the RPM Air-gap is a high rise dual plane intake. do you have the motor installed already??? if not, i would take the advice already mentioned and look to a smaller cam unless you plan on driving at 6000 rpm all day. if the car is...

Rob, what is the duration at .050"?? advertised duration can be tricky to judge due to ramp build angle. i am guessing it around 230/240 at .050". if so, that is a huge cam for a 350 on the street. with the single plane intake, that cam will be very soft on the bottom end of the rpm...

Tim, with that build i would lean to 2 1/4" exhaust. it will give you better throttle reponse and more low end torque. clearing the rear diff is an added bonus of smaller pipe. if you plan on replacing the heads and turning the motor to 6000 rpm, then look to the 2 1/2" system. as for...

Franklin, give these guys a look, they make great heads. http://www.airflowresearch.com/ as for your request, it will be hard to run 13 flat with an L-48 lower end, CA emmisions leagal and full weight car. it can be done, but may get a little spendy. first off, your exhaust is killing...

Glenn, have you checked your rotor run-out, wheel bearing slack and rotor thickness?? if the rotor is wobbling from excessive run-out or loose wheel bearings with a worn (thin) rotor, you can end up with the caliper pistons cocking sideways in the calipers. this will keep them from returning...

how is your motor built?? a mellow build will do better with 2 1/4" exhaust, and a higher HP build will like the 2 1/2" duals. Headman, Dynomax, Hooker, etc. are about the same except for the price. i had Dynomax headers in my dual system, no complaints. you may want to look at the Dynomax Ultra...

have you tried no shims?? i never had any luck shimming a Chevy starter. they always fit best just bolting them up. look real close to see if your mounting holes in the block may be cracked, tat would allow the starter to move around a bit. good luck, Brian.

what are you running for a rear spring rate?? i have the VB&P perf plus set soft in the rear. i think it is 300 #'s/in right now. the rear squats hard and the weight transfer really helped with the hook-up. i have seen guys run stiff springs and they all have the trouble you are having. you can...

i like the BFG Drags. they wear and bite better than the Mickies. have you tried airing the TA's down some?? i have the same tires on my car, and get pretty good traction, considdering. try 18-22 psi in the rear with what you have, if that doesn't help look at to the 275/50 Drags. Brian

Randy, you can put any carb on that you want, i would recommend that you go with an electric choke Q-jet without the computer control. it is a very common practice to run an older style carb. try getting one for a '78 Chevy pick-up. it seems every time you go to the parts store for some thing...

Randy, are you lacking power in the mid-rpm band?? by not setting you back, are you cruising down the road and go full throttle and the tranny down shifts, rpm go up to 3500ish and you have no power?? if this is the case, your intake is fine. the carb would be my focus. you need to remember...

i went for the L-82 high rise hood from Ecklers. it fit great, and only cost about $300 to get painted. Ecklers has the best fitting fiberglass from all i have heard. hope it works out great for you. Brian

Ed, we all thank you for the compliments!! i imagine you will have loads of info to bestow on others in due time, it all comes around. i don't know if you have seen this or not, but it is a video clip a buddy shot for his snowmachine movie. pretty fun making it, but i lost two tires in 15...

the conversion is time consuming and can lead to unexpected expenses, but it sounds like you have most things covered. the rear gear is a little tall for performance, but since you staying with a three speed it will help with economy. the 502 makes enough torque to pull a 3.08 and still be a fun...

sweet!! glad to hear things are working right!! very clean install, looks good, my compliments to you. Brian
