85 Cutlass Brougham
- Sep 1, 2006
This may seem odd, but back when I first did the engine swap on my 85 Cutlass, I built the engine with pizza delivery in mind. Back then, it had a 231 V6/TH200C 2.41 axle combo in it that left alot to be desired. So, I built this 355 Chevy with driveability and mileage in mind. The specs are as follows: .030 2 bolt main block, cast crank, stock rods, ARP rod bolts, Cast rebuilder pistons, 9.5:1 Compression, World Porducts S/R Torquer heads with 2.02/1.60 valves, a Crane emissions cam for a 305 with 210/216 duration, 440/454 lift and 114 degree lobe seperation, "Z-28 " oil pump, Edelbrock TES headers and Y pipe going into a single 3 in cat and going back to a Dynomax catback. It had a stock 305 aluminum intake and a computer HEI that were leftovers from a 406 swap in a friend's 84 Z-28 as well as the rare factory dual snorkel air filter housing and ducts that I topped with a Monte Carlo lid so I could run a bigger filter. I also used an oil cooler setup from a 9C1 ( police) Caprice. It originally had the E4ME Q-Jet and computer from the Camaro as well., and was wired with a Grand Prix 305 harness. It actually ran pretty good, breaking down but once in the 50k miles I delivered with it in the next year ( don't use bargain rocker arms!). I have since added a $15 Edelbrock Perfromer I scored at a U pull it yard and a non computer HEI and Q-Jet. It has great low end and pulls nicely all the way to 5500RPM, but I am left wondering if I could do better now given all the advancements in parts that are available. I am thinking about a roller cam and aluminum heads, maybe a different intake ( has to retain the Q-jet and air filter housing- I hate open elements, too much maintenance), or even stroking it to a 383. I can get roller cam 350's on occasion for $75 for the shortblock ( same junkyard), but was wondering how anyone else would build an engine for these conditions? Has to have a smooth idle ( right now it idles at 750rpm), decent fuel mileage, able to have most minor tune up items replaced with parts store pieces, etc. What would you do to improve the current combo without sacrificing driveability ( and without nitrous)? Oh, it has a TH200 4R and a 3.23 rear going back to 245 50 16's, and is fully optioned and must retain all the luxury stuff and A/C. It's kind of an academic question, but I am interested to hear comments and suggestions as I am currently working on the car and trying to run 13's.
