It's time for motor upgrade

Post by Purple RS »

I broke the 305 in my 89 Camaro this weekend. We had an F-Body get together in Portland to run on the rollers of a local dyno shop there. I'm almost stock except for headers and open element air cleaner. My first run was 163HP and about 240TQ and immediately after was 125HP and about 210TQ. Last year's best was 169HP/250TQ, I have since upgraded the ECM to a very tunable on the fly EBL Flash and should have broken 170HP.

I broke the motor for a single little wire that came disconnected prior to the run. The sender wire for the fan switch came off, and the motor got warm and apparently spun a bearing. I haven't looked at it yet, but it knocks pretty good.

Now my upgrade plans have been accelerated to begin in the next couple of weeks. I've scouted the area and found a shop (Bowtie Performance) who sells rebuilt motors with a 2 year warranty, and has a very good BBB reputation. I'll be contacting them to see about a long block 350/383 with roller cam to put under a TBI. TBI because all the wiring is the same and my ECM is so tunable for TBI.

I have a friend locally who bought a 350 TPI motor from them for about $1500, so the prices seem pretty reasonable. Shopping tomorrow :cool:

Well, I ended up shelling out a bit more, but got such a nice motor being built. I don't know all of the specs, but I'll have a data-sheet with them on delivery. The motor is a TBI 383 with roller cam, Scat crank & rods, Speed Pro pistons, high volume oil pump, Vortec heads & intake. Plans are to top it off with a 454 throttle body. The motor should be good enough to break the T-5 transmission I have now, especially if I'm not careful.

Name yourself for growth. That unique selling position that you have honed down to a very specific market and product may not make a very good business name. For example, the name "Joe's Music Store" would limit your business. Someday, you might want to add videos and ebooks to your product line

It was quite the summer project, working on it only weekends when the weather permitted (I was in my driveway). I finished up about the end of July and have driven it pretty regularly since. Can't seem to get a hold of the builder since asking him some questions about some tuning parameters. Still haven't got a build sheet from him, I won't have any HP/TQ numbers until I dyno sometime this winter/spring.

This is me on the way home from that fateful dyno day...

I found a website that does custom emblems in polished stainless and had a set made to replace the RS emblems that were on the car. Very good people to work with, I contacted them through their website explaining what I was looking for, a couple of e-mails and phone conversations later, I had some custom "383" badges for the car.

That's nice. I wish I knew more about that stuff. I know just enough to be a danger to myself and others around me.

Thanks, but I don't know much myself. All I did was pull the old motor and install the new one (fully assembled). My biggest obstacle was making sure the harness maintained the connections to the correct sensors, not all were in the same lace with the new intake. I still have a little way to go with the tuning aspect, but I've got an upgraded stock ECM that makes it easier to do.

I drove to Detroit from Texas to have a speed shop up there tune my ecm and tcm. Well, I was headed to wisconsin to visit family and I detoured several hours to Detroit to get the tune done. Well worth it. :)
