I posted this on another site, I wonder what the remarks will be in here 
I like how you guys sometimes display your opinions lol
I keep changing my mind about how I want to build my engine... Well that's me I can change my mind every 5 minutes when it comes to my car, I want it all...
But I've thought about it and I spend more time on the street than the strip so I should keep the power band in the 1500-5000 range. Kind of pointless to have a 7000rpm engine to be used on the street. Last summer my car hardly saw over 2000rpm on the street, and my best time at the track was done shifting at 4800rpm, I hit 99.47MPH!!!!
Anyway I have the heads, they are ported C9 heads 1.94/1.6 stainless Manley valves, I know they are good because they brought a heavy AODE 95 Mustang to 13.5 on the 1/4. I also bought some 1.6 roller rockers.
The bottom end is going to be a freshly build 306 using stock crank and stock (shot peened) connectings rods and some Probe forged pistons. I will use some little tricks like smoothing out the lifter valley (maybe polish too), opening the oil filter hole in the block, windage tray, etc...
I'm also thinking about going 347 since the base will be on the work bench anyway, might as well put in some extra cash get that all done. I'd get a cast crank since my engine will never see 400hp anyway. I know the heads and intake won't make a healthy 347 but I'm sure I'll gain some torque with the extra cubes anyway. Later on I will change the HCI once I get out of my "sleeper" stage and the bottom end will be prepped for more serious HCI...
Now for the intake, I think I want to keep the stock intake for now. Why? Because they are okay up to around 5000rpm when properly ported. Nothing like runing flat 13's or high 12's with a very stock looking engine lol I could try this anyway, I mean it takes about 30 minutes to change the intake manifolds if I see that the car is too slow. Flow numbers aren't everything, too much flow can make a 5.0L useless, I like the flat torque curve a stock ported intake will give me. The car will be a killer on the street. I'm currently looking for someone who will puddle weld the intake so I can open the ports more. Besides it's a good learning experience for me since stock intakes are worthless on the market. Oh and I have a truck fuel rail in stock and I'm going to use a better aftermarket fuel pump too. I plan on 24# injectors and a calibrated MAF. But I will get a dyno tune to make sure I get every little drop of power I can get...
The cam: Still not 100% sure, I want to get the heads on the bench flow so I can calculate what would be best. I'm guessing my CR will be around 9.5:1 but I could try and get a 10.5:1 CR and use a higher durration. I'd keep the LSA at around 112 as to not lose low end power. But I need to calculate everything, I'd like the valves to work as fast they can. Lift will depend on the flow testing but I know I don't want anymore than 530 range. I may end up with a custom grind cam for the application.
Basically if I can build an engine that will be in the 280-300 flywheel HP range (remember: flat torque curve) in my coupe with 3:55 gearing and all the weight reduction - it would be a pretty decent runner. Plus I do stuff like indexing my sparkplugs, thin synthetic oil, etc... to get every little drop of usable power out of the engine. The main thing is that the engine will look stock except for my shorty headers, CAI, underdrive pulleys, MSD 6AL, blaster coil, electric fan and cute spark plug wires and MSD cap lol Make people with unbalanced combos running in the 14's scratch their heads
The body will have lightweight wheels, tubular k-member, aftermarket control arms, aluminum driveshaft, off-road x-pipe and turn downs (no tails), etc...
My goal is to hit flat 13's and maybe touch the 12's a little lol My best time with the "stock" engine so far was [email protected] with a very nasty 2.20 60ft... Plus I'm having some fuel starvation problems, my engine will ping like a mofo at the higher RPMs... Upper mid 13's are possible with my MPH as my car sits now with the very little I've done.
Mustangs rock
That is all, if you've read all that and not sleeping, kudos
