As requested, everything I know about cars (x-post from projectcars)


The way we are going to set this up is by sections so you can skip around if you aren't interested. Keep in mind this is information I have gathered, I am up for discussion but please do not accuse me of spreading the wrong information, just hit me up and I'll look into it. Also if any of you guys ever need help, let me know ill answer any questions you may have (statement stands forever).Engines-PontiacPontiac is what I started with and have grown to love due to it being different. Building these types of engines is very different from that of a Chevy or a Ford.-301 this guy right here was Pontiacs last big block before gm phased them out of production in the muscle car world, it's not very performance oriented and instead makes a great conversation piece or historical vault within your engine bay. If looking for big power turn elsewhere.-400 Now where talkin'. When building a Pontiac engine it is crucial to understand that they were not meant to be high rpm screamers(obviously they can be made to be) instead they highlight torque which is that oh shit feeling you get when you floor it from a stop light.achieving greater torque is done by increasing stroke. This is known as "stroking" an engine. Effectively you are making it larger so that it can incorporate more air and fuel which is the basis for more performance. I personally favor Eagle stroker kits because they supply everything needed for bottom end, and they increase the displacement all the way up to 512 cubic inches with smaller kits inbetween. The camshaft of choice for large displacement Pontiac engines is the summit 2802 (best for 455 inches and up, anything under use the summit 2801 cam). With this combination, the car will haul ass the second your foot touches the pedal. One thing that you'll have to think about your use for the engine. With stock heads, it will run out of power at about 5500 rpm because they don't flow very well. You can either port them yourself(more on this if you ask) or purchase new aluminum heads.455The 455 is built in a similar fashion to the 400 and will yield similar results so there is no reason to write more under this.-OldsmobileThe only v8 engines that are worth talking about are the 442, 403, and 455. The basic principle is that if you throw enough money at it you'll go fast. This is due to the fact that the blocks are not built very strong and will require altering such as cement filling or sleeves if you are seeking high compression. Performance parts are expensive because of the limited availability of Olds engines. If someone is looking to build a bracket car or dragster out of an olds I can always write more if you pm me.-ChevyWelcome to the king of cheap performance parts. Continue reading if you want big power for an attractive price.-350This might be the most popular engine of all time, and for good reason. 500 horsepower is a simple feat and at an affordable price too. Summit makes a kit that includes components such as heads, cam, and rockers that will allow you to hit that number for right around $2000. Many things can be done with these engines but it seems that they favor a higher rpm build. As always you can stroke them to a 383 to achieve more low-end power. Roller cams shine particularly well in this type of build. There are a lot of routes you can take and I love every single one of them. If any of you guys ever have a crazy idea or even a simple one pm me and we can put something together.-454 The big boy in the Chevy world (in relative terms cause chevy makes a damn 572 crate engine).Make people will simply throw a cam in these guys to wake them up which is more than enough for many. Raising compression also allows for a more aggressive roar. 10.1-11 is the highest I would go for street ability. 600hp is an easy goal for these grunts.-LS FamilyIgnore the LS1 but anything else is good to go. I personally favor the LQ9 due to its ability to handle higher power than the aluminum blocks.The way you build an ls is through 3 paths. One is displacement the other is high rpm, and the 3rd is through forced induction. Displacement has already been beaten to death in this write up so pm me if something is unclear.High rpm: Decrease stroke to make the engine 4.9 L and then get higher compression pistons and better flowing heads. (this is dumbed down a ton but it's a simple recipe)Forced Induction: If you've ever heard of those 1000 LS engines, well this is how they do it. Decrease stroke to 4.9, get forged pushrods (you can get forged everything but it isn't mandatory) and strap on the turbo of your choice. Please be advised that anything higher 900 hp will sacrifice some dependability.-FordFord engines are in the same field as Pontiac and are kinda expensive to build the older ones like the 390 up to the 460. They can handle large power but I am not exactly sure how that achieved. I'll research more and get back with some info.Coyote engines are where it's at if you want performance. Some have been pushed to 1100 hp on stock internals with forced induction.-Dodge The Hemi is so rare that I prefer to leave these guys stock, I'm sorry if this offends anyone but it's what I think due to its personal connection with me.(always willing to help though)SuspensionThis will be focused on drag racing so bear with me.Front suspension: I would personally run 90-10 due to it being the best ratio for weight transfer to the back tiresRear Suspension: Slapper bars are the way to go because leaf spring love to flex during launches. What they do is basically put a stopper on the springs that restrict their flow of motion.Frame: No matter what type of car you have look into subframe connectors. They help stabalize everything and help prevent the body from twisting. Fbodies are notorious for this but its always a good precaution.TransmissionsI'm familiar with the Turbo 400 and Turbo 350. Both are stellar transmissions that can be made to perform well. A shift kit is a good start but you should either spring for a performance built tranny or rebuild it yourself with a performance rebuild kit. different kits are available depending on your power levels. Here comes an interesting argument when bracket racing, is a 2-speed transmission better than a 3 because you only have to do one shift? It helps eliminate user error with miss shifts and wrong rpm shifts. If you want to drive these guys on the streets then there is a gear vendors unit that incorporates an auxiliary overdrive so that you can cruise at under 2000 rpm for highway purposes.As I think of more things then ill add them via /r/cars http://ift.tt/2wcfiWR
