Hey guys! Well, I’m really thinking about pulling my Chevy 350 small block out of my 1991 Suburban, and giving it a nice rebuild and upgrade. So, I’m coming to ya’ll to give me ideas of how I should proceed with the rebuild. The goal is to at least match the horsepower and torque numbers of the Chevy big block of the era. More power than the big block of the era’s all cool, but I need to at least match them. I think it’s doable. Chevy’s power ratings for the small-block that year was 210HP@4000RPM and 300TQ@2800RPM. The big block was rated at 230HP@3600RPM and 385TQ@1600. Now that I looked it up, I know I can easily blow by the big block numbers… Now for the important part…money. Let’s assume I can spend roundabout 2 grand on the project. My primary application for the motor and Suburban are cruising down the highway at 70mph while getting the best MPGs possible, and towing my camper that weighs, let’s say around 11,000 pounds. (The weight is an overestimate I hope, but let’s just say that…) The truck also idles a good bit, so it needs to be idle-friendly. It’s backed up by a TH700R4 transmission that will be rebuilt/replaced with an upgraded unit in the process and a 14-bolt full-floating rear axle with 4.10 gears. Now that that’s said, let’s lay down a few ground rules: No carbs No full-fuel injection systems, throttle-body injection only The engine must be able to be fueled by a throttle-body injection system compatible with the stock computer (with or without a custom chip burned for it) No swapping to a big block In your cost-analysis and speccing, assume that I have a 2-bolt main block which will most likely need/want to be swapped to a 4-bolt main block. I was thinking things for this build along the lines of a bigger cam, new pistons, rings, rods. Fueling is a problem on my mind. I don’t know if the stock throttle-body will be able to dump enough fuel. Perhaps there are bigger injectors I can get for it. I heard there’s a mod where some people have been using big block throttle-body injection setups that work with the factory computer somehow. I’m open to moving up to a stroker, but I don’t think I can fit that into my budget. I’ve never built a performance engine before, so I’m clueless as to what parts are good, what parts are better, what brands to lean towards or shy away from, and what is useless for my needs. I’m also wondering if anyone knows of a good performance transmission company that can get me a heavy-duty 700R4 transmission that will stand up to the abuse of towing that much weight. I do have plenty of cooling and outboard filtering of the transmission fluid already.
