So I'm building my first engine, as in a previous post, I passed on the 305 headsBlock is from what I can find an 80-85 w/ cast# 14010207Budget building for power, I've ordered a book, but it hasn't arrived yet, but also figure with the internet, I can probably get more answers than a book.I'm considering the 96-00 Vortec heads. Thoughts? Compatibility concerns? are ALL 350's from 96-00 the Vortec Heads?Anyway, if I find a set of heads that a seller claims are these vortec heads, how I can identify that in fact they are Vortec heads?
12558062 350 98 1.94/1.5 L-31 Vortec truck 64cc chambers 170cc intake port 12558062 305/350 96-up 1.94/1.50 68cc Vortec Look for these casting numbers. Just because they are center-bolt heads does not mean they are Vortecs.In stock form Vortec heads will only tolerate about .480 lift. While you can modify them to accept more lift, the port flow will run out about 5500rpm.
Most of the information you already have.1.1980 to 1985 3502.Low Horse Power Rating3.4 Bolt Block4.Came out of a truck.Check the crank for any forging numbers. It may only have a cast crank if it was in a 1/2 ton truck....BobNO RICE BURNERS ALLOWED!
there are many good books that are very very helpful and easy to read and understand. David Vizard who I think should be called Mr. Chevorlet has several books on SBC one I find very helpful is called How To Build Max-Performance Chevy Small-Blocks On A Budget. If you understand all the information in this book you will ask very few questions on these forums. It is very easy to read and understand. If I can understand anybody can. As for the SBC it can produce more power than most people can control on the ground. Also this books gives common builds from low power to high powered engines. I'm not a sales person for them just a lot more knowledgeable person because of these books. Ask me some questions. Shakerag
Most everything centers around the all mighty dollar. Starting with a goal is probably the cheapest way to go. Even though you may not complete this engine from start to finish planning a direction is by far cheaper than buying parts without rhyme or reason. Shakerag
