Gas engine is wimpy. What to do?

Dear Eric,

I have a 1987, 460-powered 36-foot Foretravel Grandvilla pusher with an Allison 643 four speed. It’s low on power. It has big headers, 2.5. inch exhaust on each side and an Edelbrock four barrel at least 750 cfm or more. Has anyone turbo charged a Ford 460 with good results? I’m thinking about adding small twin turbos at the far end of each header just before the muffler. The reason is there would be a little less heat. There is no room for an intercooler. What do you think? – Tars Campbell

Dear Tars,
You have a great idea for getting some serious power with your 460 Ford, but it’s not very practical. To make it really be dependable would take a lot of time and money. I would suggest, instead, that you take that money and install a 5.9l Cummins diesel engine. It will adapt up to your Allison transmission and can make 300 hp. With a Banks Twin Ram power PAC, it would run forever and get better mileage. I think that with a little effort you could find room for a inter cooler, too. If you like this idea I can suggest someone who is qualified to do the job correctly.
