|I started to read the postings and determined that everyone has there own idea of what to do !
- Get the 331 Kit, but without pistons, stick to stock Bore if possible, you end up with a 327 CI SBF but to me 327 is one of those cubic inches that just works. You will end up with good power and a little more reasonable manners on the street !
- When you get your stock pistons, look for somewhere around 9.0 compression, more than that will require higher priced gas, lower mean less power, add some "Oil Slingers" to the list, a little extra oil in the cylinder helps on the SBF. Wrist Pins is a good thing.
- If you get a stock block, consider a Main Bearing Strut System, which will lock the Main Bearing Caps together, it helps to make the Block more ridged.
- If you happen to have a large amount of cash, an SVO Block, either a 5.0L or a BOSS 5.0L, both nice block but pricey $$$$$$ !
- Camshaft, I like a good strong cam, like the sound of the overlap in the exhaust, but it can sometimes cause difficulties on the street so don't go too big if you want good manners on the street. To me to gain a little extra power from the cam consider a shorter duration, but more than stock, but with a higher lift but not too high, 0.600/.050 is a little too high for a DD, but 0.550/.050 with a shorter duration , now that could work. Little extra lift can equate to more torque on the low end and more HP on the high end of the rpm scale. Choose wisely, get your ideas of how you want the engine to do, what weight is for the vehicle, and then contact a cam manufacturer for suggestions. Ask the Tech questions about performance, will it work with my transmission, my gears, my induction system, will I need a Mass Air System, and is there a quick setup, get it together now not later.
- If you decide on a more standard type of camshaft, you can gain some low end torque by replacing the Rocker Arm with a higher ratio, I can not remember the exact ratio that is stock (thinking 1.6 to 1) but but going to the next higher ratio will help and MAY cost less than a new cam. Look up the stock rocker arm ratio and go higher... ! Roller Rockers will help to reduce friction but cost more money but something to think about !
- Induction Systems vary but the OEM 5.0L EFI is good enough for 350 to 400 HP without a lot of additional mods and remember too big is not good, but the Mass Air System on the incoming air is the best.
Before deciding on the exact setup, decide on the gears you want to run, the tire size, and what you expect from the finished engine.
This list is not a list of the right things to do, because as stated before, every engine builder has their own ideas, I build my street engines for mild manners but good low end torque where you can feel it when you hit the throttle and you can get by with a mid grade gas not the high end gas or the price.
Also, when having the block prepped, if funding is available, think engine balancing, it will surprise you at the results.
Good Luck on your choices, there will always be tweeting, no matter what you do for mods.
