If you have junk heads, then it's gonna be tougher.Īnd, if you would read my post a little better, you would see the roller setup is on an engine producing 450hp, not 300. Sure it's possible to build a 300hp SBC with mostly factory parts, but it depends on what you start with. Who the hell wants to adjust the valves with a solid cam? A hydraulic is the way to go for sure. A solid lifter cam is also an incredible waste on a street engine, especially one at the 300 hp level. The Q jet is a piece of shit that is difficult to tune because of what kind of parts are available for it, and most of the ones out there are the 70s and 80s smog carbs, and those are even worse. And you'll notice that chevy's 300hp crate engines are usually using one of those 2 heads.
Listen to what you are saying.exactly where are these "2.02" heads you speak of? There have been NO chevy heads built in 25 years that have those valves, not even the L98 aluminum heads or the vortec heads, which are by far the best factory ones.
If it's your hobby, that time = free horsepower. Sure, you can throw a bunch of off the shelf parts at a project and make something fast and expensive - but time = horsepower too. A few hours porting and polishing with a die grinder, a set of 1.73:1 351 rockers from the junkyard (and another $24 to get the pedestals milled), and I had a car that was easily pumping out 75hp over the stock 200+. I put an 87 mustang hatchback (with t-tops) into the low 13's without buying a fucking thing except the $20 I spent on a pair of '65 289 heads and the $60 I spent getting them milled. Stick a $100 edelbrock intake on a set of mildly ported and well polished 2.02 heads, a good solid lifter cam ($99 cam + lifters) and a well tuned quadra-jet (one of the simplest, most reliable carbs you can get on ANY car) and you can pump out 300hp/350lb/ft on 9.5:1 compression and pump gas. No edelbrock, no holley, no roller fucking camshaft - just good factory parts and attention to detail. You can build a 350hp 350 chevy from bone stock parts. You raceboys have been brainwashed by too many HOT ROD magazines.

since i'm not overly concerned with going monstrously fast ( i know i'd kill myself or lose my license within a year if i went for my original plan of an ls1/t56 combo), i can concentrate on reliability and fuel economy. even on the low end, i'd have about 10lb/hp, which is three times better than the power to weight on my current truck. ygm View image: /infopop/emoticons/icon_smile.gif i need to get over there more often! several of the big guys there are within an hour or two of me.Īs for the offer. i'm there as pauli, though almost all of my activity was last winter. Superdave: i thought you were one of the other hybridz'ers at ars! w00zy and i were trying to figure it out. that's somewhat out of the budget, though it is a projected victim vehicle, should i ever get finished. So, how much do you guys think this would cost? i'm somewhat fond of an all edelbrock performer setup, since from what i've seen they're reliable, efficient, and produce the sort of torque curve i'm looking for (strong from idle on up).Īlso, any favorite books on building an sbc? i realize it would probably be cheaper to pull one from a junkyard or get one in a crate (warranty is nice!), but we want to build the damn thing ourselves. I'm wondering how much it would cost (in terms of parts, since other than opportunity cost, labor is free, and tools aren't really factored into this) to end up with a 350 on an engine stand (so the cost of the engine stand would need to be included, since i don't exactly have one laying around). but that's beyond the scope of this thread. parallel to this, we're also hoping to build a mild 350 in my garage. this coming spring, a friend and i are hoping to take some automotive courses at the local community college. I've been meaning to post this for a while.
