Not a good day at the Bender house, cannot get the alternator low enough, the clear the hood with the aluminum valve covers. My 1.6 rockers will not work with stock valve covers, so I guess I get to go back to stock rocker arms so I can use the stock valve covers to get the alternator were it belongs. I do have all accessories where they belong other than the alternator. So I back up two steps and drive forward
I wish I had done mine like that. I didn't want to screw up anything though so I kept all the pins I needed in place and just pulled the ones that didn't have anything to do with goin fast! So, my computer sits in the space normally occupied by the vapor canister at an odd angle secured with a couple bungee cords. When I get back at it I'm going to build an air cleaner box that the S-10 puter mount I bought will bolt to the top and have the filter under/inside. For now it seems happy where it is and I'm having too much fun driving it!
Thought that I would give you all the history on this mod (LT1 with a TPI intake). I'm an old hot rodder built my first V8 at 15 an old 327 large journal. Lol amazing how you don't forget that kind of thing. At any rate, when the TPI came out it was a game changer on the street scene. Massive torque out of a 305, completely nuts to me. I am an ex Holley junky, so ya what the heck is this TPI stuff? Just like my Holley days if there was a tech article or expert documentation about TPI systems, I read it. Then came the LT1, bigger torque numbers, with an inferrior (torque wise) intake. What did these fools do? Make a deal with the dark side? I started researching this monster LT1. I learned that there was a lot to this new motor. Reverse flow cooling, which allowed for higher compression numbers. Sequential port injection low in the RPM's improved fuel atomization since fuel wasn't pooled on top of the valve (batch fire issue) the aluminum heads used the same combustion chamber design as the 69 302 heads, tried and true. And lastly a better, faster ECU. Then I started running simulations in my head of how to combine the two and what would I end up with? Long story short a gentleman turned me on to the LS1 ECU and how flexible it actually is. And I found out that the TPI manifold will set on the LT1, and that the ports actually match up. Well the rest is history. I'll look up the dyno numbers for a POORLY tuned pull. They are interesting.
Okay I'm going to start throwing out the technical stuff for those of you watching this. In order to use the LS1 ECU on an LT1 you have to lose the optispark, Dorman makes a freeze plug that is 2.88 in that will fit snugly in the hole where the optispark went that solves that problem. Next for ease of operation I took the LT1 coil off of the mount, and mounted a Vortec 5.7 coil in this place. Next thing you'll have to do is pull the stub shaft that drives the oil pump, and then install a Vortec distributor. I pick up the aluminum housing Vortec distributors off of eBay for 50 bucks, then trash all that Chinese ignition and put in ACDelco Quality Parts. This gets you passed and way from that POS optispark. The Vortec distributor will work fine with the TPI manifold everything is in the right spot.
I have a LM7 5.3 pair up with a TH350
I need opinions on oil pans, Im not looking to spend $350 for an oil pan when the damn motor cost $500.
So please give me some info on budget solutions.
I understand Holley pans are solve all problems but is there anything else out there?

Hey y'all. I have recently been having problems with the choke on my quadrajet. I let the engine warm for quite a while but the choke wont open and the RPMs wont kick down. I replaced the choke thermostat thinking that might do the trick, Not sure if I didnt set it right or what. But When I...
Hi everybody from germany !
I'm still in rebuildung some Q-Jets but there are 2 big questions open:
Doe's anyone knows a definated height for the Main and the secondary rods ?
At the main side I'm thinking I have the right height when pushed the power piston fully in and will be with the rods...
First post here as I recently (yesterday) acquired a 1981 El Camino Conqista with a 305 and a 3 speed auto. Diving head first into tinkering and getting this thing fixed up! First order of business is I want to get all the interior gauges working (especially water temp). So far I...
