June 15, 2011Gas mileage (after I fixed everything) is about 14 city 19 highway. 3.73 gears.
I would recommend a 218/222 or 222/222 cam (COMP Racing makes good ones) if you want to keep low end torque and not need a high stall torque converter. Here`s a good list of what you want to be looking at:
Putting a giant cam in the engine will totally tank low end and gas mileage. Staying mild is the new wild.
As far as headers go, long tubes will give you more low end torque and shorties will give you more high end HP. Both kinds will give you more torque than stock manifolds.
Cherry Bomb mufflers give you lots of noise but don`t have any real power gains to them. You`re better off going open tubes if you want noise.
FYI Notes from my install:
Timing Set- Aftermarket adjustable timing sets are the bane of beginners. Stick with OE type.
Oil Pump- You want to be very sure you put the pickup tube back in right. You MUST use a new o-ring on the pickup tube. I recommend doubling up on o-rings to compensate for any errors you make. As long as you get the pickup tube bolt tight you`re good to go. Oh, did I mention you need to drop the oil pan?
Oil Pressure- After taking pump off and reassembling, crank engine and let it run for 2 seconds. Look at pressure gauge. If less than 40, turn off. Crank again and turn off after 2 seconds. Crank again and let it run for 4 seconds. If you don`t see pressure or it`s lower than 30, you`re taking the oil pump off again to fix the pickup tube. (I had to fix mine 4 times to figure out the o-ring I used was not thick enough)
Cam Installation- Either have a professional install it, or use lots and lots of assembly lube and go very slowly. You etch a cam bearing or journal, you`re looking at a very expensive fix after your engine loses lubrication. It`s not difficult for a beginner, just be gentle. VERY.
Heads- You`ll want them to go to a machine shop and be resurfaced and cleaned. You`ll also want the shop to install the seals and springs for you. Do not attempt if you`ve never done it before.
Block- You want to keep the head bolt holes clean. If you screw a bolt down into dirt or liquid (yes, coolant gets in them if you take a head off) you`ll crack the block. Use compressed air and brake cleaner to clean them out.
Head bolts- Must use new ones
Crank bolt- Must use new one
Gaskets and Seals- Must use new ones. No Insta-Gasket or goop crap. Head Gaskets must be Multi-Layer Steel.
Torque specs- Must be followed. It sucks to have to disassemble a head after you forget Step 3 and start the engine.
Help- You`ll want friends with specialty tools. Beginners should not attempt by themselves unless they have money in the bank and a spare car. Also, do not involve any other alcohol besides antifreeze. Disastrous results may occur.
