My holley blue just shot craps the other day. I didn't even get one year out of it. I threw another one on because I was in a hurry(daily driver). They work great but was not impressed with how long the first one lasted.

Yes I port. I don't go for maxxed out porting. As I stated before I'm no expert. I flow test every head I port but posting numbers IMO really don't do much because every bench is different along with what you use around the intake port, weather(actually seen 10cfm difference on same bench with...

If you don't mind playing with putty then nope. All critical dimensions are basically the same.

I'm no expert but I'll give my two cents. Water jackets limit porting for most. They vary from head to head and year to year. Most like the J or X for the bigger valves(less money) and they flow good in stock form but they have bad exh. ports. The closed chamber 302 have small valves but you...

Not too sure what holes your talking about. The three closest to the headers should be no problem. The two closest to the intake have extra meat on the bottom that are visible in the intake port. If you drill and tapp these to a larger size for the heli coil you might break threw then you need...

Just talked to a friend today and he along with about 6-7 racers(from IN) want to drive over there. They all run around mid to low 9's in the 1/4 so there will be some quick iron there. Keep us posted with dates please.

My old ones were 69.4-71.2 I have some flow numbers if you need them.

I think running that at the strip is a great and safe way to tune. Unless you have an LM1 your kinda hit and miss with air/fuel ratio. You could go to the track and start playing with the timing like...start out low(32) then keep going up by two degrees until you lose mph then back it down...

I just found out that my dad use to race over there in his younger years. I grew up in Taylorville and never even heard about that track. I plan to be there and would love to race my dad again. He has a 440 which is slower then my 340 but I'm porting some heads for him right now so he can drop...

What coatings...inside the block(valley area), rods, cranks, pistons? The coatings for the rods and cranks are expensive plus the cost of shipping the part back and forth. There is not much to gain unless you spin past 7000rpm. The lifter valley and such serves two purposes as far as I...

Cylinders 1,3,5 and 7 the major is the side of the cylinder wall closest to the lifter valley area and the minor is toward the outside of the block. Cylinders 2,4,6 ad 8 the major is toward the outside of the bock and minor is towards the lifter valley. Another place to sonic check is the front...

I've always heard and used the .200 min major and 1.50 min. minor. I know some go thinner then that but in the end its your money.

The info will be on the sheet you get with your rings. I would gap exactly what it says unless your running KB but your not so no worries.

Just curious.

The pic is my carb. I have no choke or anything like that. I simple put in a proform main body and that's it. Only thing that needed messed with was acouple holes for the rolled pins were alittle too shallow and some holes on the base plate were in a different location but demon gaskets have...

Agreed. They wanted me to send in the old one before they "could" sell me a new one.

They do interchange.

Well I like the idea. Big cubes and small everything else. It would make a killer street motor but will nose dive around 5000rpm. I say built it and ditch the tunneral ram and go with the performer RPM manifold. I do agree what was said before that it's not the best combo(your leaving a ton of...

Well since you had it rebuilt my guess is you had it bored and now that you have thinner cylinder walls all that heat is building up in your coolant and would cause the temps to be high...............just joking but I had to throw it out there. My guess would be improper tune...too much/little...

I bought a similar gauge awhile back and had no luck. After readings some stuff on O2 sensors the cheap ones only read from 13-14.7 which my car doesn't even run in that range. I borrowed a LM1 from a friend and dialed the carb in and then gave it back. Also I'm not sure what you mean about the...

I came up with the same thing as you did. Great looking heads...love those ports. Any chance you flowed those yet?

The rocker tracks really good threw the sweep. I had to keep milling the heads to get it just right. Thanks for the link.

I must have got some bad info then. I was always under the impression that the weight of the valve, locks and retainer was pretty much the limiting factor of RPM ceiling granted that had the right spring pressure. But you can only put so much pressure on a solid flat. I run jesel rockers by the way.

OK I know there is no clear cut answer on this but I would like some opinions. Lighter valvetrain equals higher max RPM without valve float so.....how much does it really matter? An example: A small block with some normal replacement stainless valves, locks and steel retainers against 5/16 stem...

You just torque them to whatever your bolt manufacture recommends with the corresponding lube. I ran almost all ARP through my motor and go to them for the torque number. OEM is 95 for the heads and 45 for the intake. But it sounds like your not working with OEM bolts anymore.

I see what you are trying to do but it is going to cost you some money in machine work to turn the crank down that much. Also those cranks have been know to have the oil holes move outward too much when turned down to 318 mains. Your thinking that a 318 will rev faster then a 360 is not really...

Thanks for the info. Just really didn't want a constant drain on the battery or that alternator energized all the time.

There will be a drain on the battery hooked up this way and I want to get around it. Just need to know if one of the OEM wires from the voltage regulator will give 12 volts all the time(I'm only hooking up one wire)

I just bought a small alternator and it came with a jumper wire for the field to make it a one wire alternator. It says in the instructions that with the jumper wire the alt. pulls 300mill amps. I could just run a whole new wire for an ignition point but don't want to. So I was wondering if I...

Why is there "spanx power mama maternity body shaper" advertisement for ebay motors on this site? I seen it off to the right and it cracked me up.
