202 heads, no assecory hole...what to do?

Hello,

I have been working on a 1970 chevelle for over 2 years now. We are currently assembling the motor that has been set in the car with nothing on the front (fenders, core support, inner fenders...)
We purchased a rebuilt 350 modified to a 383.
We were given 202 heads with the motor and are using those.
Just installed new edelbrock intake and carb so I really don't want to take all of that back off...

Then as we were attempting to hookup the alternator we said "Hey! There is no hole!"

Didn't realize it before. What should we do about this? Is there another easy way to mount the alternator and power steering (no a/c)? Are there some brackets I can buy that are specifically made for this? I would hate to have to make some...

If you need some pics let me know and I will post some...

Thanks,

Joe

They have the brackets you need.

If you can get brackets to make it work that would be best. Most folks will tell you that you cant drill the holes because the heads will break and in most cases they are right. But I had a 71 blazer with that situation and made it work. The trick is to make spacers that are contoured to the shape of the head and to be absoloutly certian that you are in no way placing a bind on the head. It has to be very secure and carefully done, but it can be done.

I have drilled and tapped holes in my old fuelie heads with out any problems.

and I have also used an aftermarket bracket that only bolted to the water pump.

both worked equally well.

drilling and tapping a hole is cheaper. and you will need to use rtv on the threads that go into the head. drill a "straight" 5/16 inch hole and use a 3/8-16 tap (high speed tool steel, not a carbon tap). coat the tap with grease to catch the metal chips.

My 82' truck has had several engines in it over the years. At one time it even had a 340 H.P. 327 in it. That motor had "fuelie heads", without accessory holes; I used the trucks stock bracketry, and fabbed up some "connecting" brackets with straight stock. Worked fine, looked hokey, did'nt cost anything except my time. But, quite frankly, it looked a whole lot better than those Alan Grove high mount brackets.

Ya don't need to do anything. Just use a bolt and nut instead of the long bolt and spacer (that goes to the head).

I've been doing it that way for 20+ years with no problems.

I got those brackets you need, check your PM. The little bracket bolts to the bolts that hold the water pump to the block. The big bracket bolts on to 2 bolts bosses on that pump. The alternator goes in between the 2 brackets. Nice and clean and no holes to drill.

Thanks for the info. I am probably going get some brackets. I did check out the alan grove website and some of those high brackets are out of control. And paying $90 for a 5" x 5" piece of metal makes me nautious! But at least I can complain to someone else if it doesn't fit.

I also need a bracket for the power steering pump.

Thanks,
Joe

those are alan grove brackets. I have the one for the ps also. check your pm.

Yep....have done it many times. Once the other brackets are tightened up, it's fine.

I have built brackets with a drill, a chopsaw, some 1" wide flat stock and a welder.

Basically I built a strap that goes behind the alternator, It was mounted to the intake at the top and either the header bolts or the front bolt holes on the bottom of the front of the motor. You can just drill a hole or put a 3/8 tap in the strap and run a bolt into it You can even mock up the rest of the brackets and install the alternator and use it as a template so you know where to drill the hole.

Same thing with the Power steering pump bracket. It cost around 10 bucks in steel and around 4 hours to do the whole thing. If you do it right it looks stock.

sell those crappy heads and get some that make power...

Here we go again!

I am experiencing the same problem with the engine that I am building, but it is by design. My heads are a set of Double Humps that came off of a early 70's Vette with the 1.94 valves. What I am doing is using an alternators that is mounted on the bottom from the water pump. I purchased my set from Summit at a real reasonable price. If you are using a long style pump then use the brackets for the long pump and so on. Easy fix. A lot easier than going through the worries if your going to ruin your heads or not.

machine shop tom is right ,simply use a nut and a long bolt , i have those same heads and i drilled a complete hole through alt and installed a nut and bolt , im also running a serp belt set up from a 87 chevy caprice and i havent had the first problem , good luck ,birdman92
