This site is dedicated to the restoration and preservation of 1960's and '70's Musclecars. I will answer any and all questions about what is original, and what are "Period Correct" modifications. I will also post my personal opinion about what is and is not proper. People are encouraged to debate me or share their own opinions or experiences.

Some "Rodney Dangerfields" that didn't make the list....And Why....
Comedian Rodney Dangerfield always joked that he got "No Respect". That's why I called some of the overlooked engines in the last posts "Rodney Dangerfields". However-as I pointed out-these engines can make plenty of power and torque for low bucks. Like I said,maybe not as much as a GMPP 572 inch Rat or Mopar Performance 505 Wedge or Ford SVT 514 or in the case of the small-blocks not as much as-an Edelbrock or GMPP 383 or Ford SVT 427-but enough to get the average Joe 12 second et's in a still pretty streetable package for relatively low bucks. I had other people suggest other engines that I overlooked but they were specifically kept off the list for one of two reasons-either they are obsolete and parts are non-existant or very hard to find and expensive, or there is a "sister" engine that is much more widely available and has good parts availability and makes way more power for the same or less dollar investment. # 1. This is a perfect example. 1968-73 307, 1977-95 305 Chevy V8. People asked why I overlooked the 305s and 307s when I espoused the virtues of the 283. Here's why-the 283 can be safely bored to 301 inches-with a 4 inch bore and a 3 inch stroke that's exatcly the dimensions of the original Z/28 302. Chevy engineers did basically the same thing-they put a 283 crank in a 327 block. Like I said a 301 Chevy can be a high-winding rocket. The small-journal bottom-end will stay together till 7,500-8,000 rpm easily and big-port "2.02" factory or aftermarket heads will fit. SCCA Trans-Am racers were getting 485 hp from 302 inches with in 1968-with off-the-shelf Chevy parts! Even 40+ years later you can't make anywhere near that power level with a 305 /307. Here's why-mainly they are both a small-bore / long stroke design. This was done to make an "economy" motor designed to get good gas mileage with a 2bbl carb and still have enough low-end torque to pull a station wagon or 1/2 ton pickup around. However-this caused two problems for people looking for high-performance-the small-bore design doesn't allow you to use the big "2.02" or even 2.05 / 2.08 intake valves of most factory and aftermarket iron or aluminum heads. The valves will hit the block. Without the big-port heads the engine can't breathe good enough to generate any serious power. And the long-stroke bottom end doesn't hold up well past 5,500 rpm. And lastly-350s are the proverbial dime a dozen and make WAY more power either stock or modified. The only thing a 305 or 307 is good for is if it's already in the car and running, and you want to drive the car while your building another engine. # 2. 352 Ford V8. While these belong to the same family-the "FE" series-of the 390 / 427 / 428-there pretty useless. The reason is-while their big and heavy-there only 352 cubes. Since 390s were used in zillions of Ford cars and trucks from 1963-76-and can be bored and stroked to 447 inches-I'd just get a 390. Or a 351W can make way more power for less money. Also avoid the 360 V8 that was offered in Ford trucks in the mid-70's. They used a 390 crank in a small-bore block and had the double attributes of no power and crappy gas mileage. Unless your restoring a 1960 Ford Starliner to the nth degree I'd forget the 352 and just get a 390. # 3. 326 / 350 Pontiac V8. These have the same problem as the 305 / 307 Chevys. They are a small-bore / long stroke design which gives them decent low-end torque, but the big-port / big valve heads used on the larger 389 / 400 / 421 / 428 / 455 engines don't fit-the valves hit the block. Some people talk about notching the cylinder bores for clearance but why would you spend a ton of money on custom machine work that may not work anyway-how are the head gaskets going to seal with a big gash cut into the cylinders?-and all other things being equal a 350 is not going to make anywhere near the power a 400 will and a 400 costs no more to buy or build. # 4. 361 Chrysler. These are a "B" engine just like a 383 / 400. However-like the 352 Ford-their big and heavy, and there only 361 cubes. An "LA" or "Magnum" 360 small-block is much lighter and makes way more power for less money for the street rod crowd. And for musclecar guys since the 383 /400s are so plentiful-and make substantially more power even stock-it just doesn't make sense to use a 361. # 5. 394 Olds V8. These are big and heavy,there's virtually no parts availability-and because 1965 and later engines use a different deck height and bank angle-NOTHING interchanges with the later 400 / 425 / 455 engines. Edelbrock makes Aluminum heads and Pefromer, Performer RPM and Torker intakes and cams for the later engines-but none of that stuff will work on a 394. Unless your restoring an early '60's 88 to the nth degree-you'd be better off with the later big blocks or even a 350 / 403 in your Olds project. # 6. 300 / 327 / 340 Buick V8. Same deal here-there is zero aftermarket support and nothing interchanges with the '68-77 350. If you have an early Skylark with one of these and want a big performance infusion and keep the car all Buick the best way is find a '68-77 350 and swap that in and swap the two-speed ST300 for a TH350-they are the exact same length and use the same rear trans mount and driveshaft yoke. If you need SERIOUS power and want to stay all Buick-( no 350 / 403 Olds or big-block Chevy or Pontiac transplants ) then you'll need a 400 / 430 / 455 out of a big car. Anyhow-hope this helps everyone out-some overlooked engines are "Diamonds in the Rough" and others are only useful as boat anchors. Mastermind
