The exhaust ports are raised .400" on the RHS heads, as you have obviously found out.

 

Wow, glad to see some guys are still checking up on this thread. Sorry for not updating it in so long. I got the intake elbow done and am wiring it up right now with sensors. I totally suck at wiring and I don't spend too much time working on it anymore, at least not like I used to.

As far as throwing on a 4 hole I did think about it because it would be very easy, but then I would lose the windsheild wipers and wouldn't be able to run any kind of air cleaner. This way I can run pretty much all the stock components like CAI, wipers, hood, etc.

Yeah, I knew they were, but I didn't think it would cause the headers to kick out like they did.

 

I've also decided that I'm going to run the fuel system in series instead of parallel, there just isn't enough room at the back of the motor and it will look like crap with fuel lines running everywhere. Probably run a regulator on the passenger side rail. I need to order a lokar throttle cable since the LTx cable won't work. Still need to do something about the exhaust, but I haven't physically worked on it in months.

 

I just wanted to add something from what whole small block, bigblock discussion from earlier, lsx powered 454 twin turbo vette, The final round I was there and he ran a 7.30 at 205 holly sh**

I need some help guys. I have a couple questions about wiring options and what you guys would do or have done.

Using a BS3 I can only control one fan. Should I split the voltage and run both fans at low speed and then put in a high speed fan switch or should I run one at high speed and a manual fan switch for the other to run at high speed?

Next question is in relation to the fuel pumps. I have a dual setup and will run one normal through the BS3. If one is enough I will run the second one manually when the nitrous is armed, but if not can I use the boost control parameters in the BS3 to activate the second pump at a given RPM? Sorry if I should know this because it's in the manual, I'll look tonight but wanted to see what others have done.

Final question I feel kinda dumb asking, but can I run a switched 12V post from the ignition switch somehow or should I run a seperate accessory switch? I would need this for stuff like the power windows, headlights and motors, backlighting for guages, etc.

 

You did install the cylinder head locating dowels/sleeves before installing the heads right?

I see they are missing in these pics.

 

I'd just wire one small fan so it's on with the ignition, and have the BS3 turn the big fan on when it gets up to x temp.

 

I have a stock set of fans, so both fans are the same size, but that does sound good, I'll just run one fan all the time and have BS3 control the other fan to keep the temp where I want it.

Got the distributor in finally, took some work but it actually fits quite nicely. Had to cut the bottom of the cowl, but wasn't bad at all. The trick is turning the wipers on so the arm rotates out of the way, that gives you enough room to drop it straight in.

 

subscribing. bad *** build. cant wait to see the results.

 

just found this, subscribing, can't wait to see this finished. Just something about a BBC....

 

subscribing.

 

WOW That is some awesome work there. Anyone that can do that stuff my hats off to you.

 

Subscribing, Nice build so far want to see wen its finished.

 

Mocking up the fuel system, will actually put it together and finish next week while I'm off work. Pumps and tank are in and I'm wiring up the relays. FPR is going on the front pass. rail and the drivers will crossover to it. The two lines running on the valley are the feed lines to the back of the rails. Feed is -8 and return is -6.

 

Awesome, If I win this 502. I got a 454 to put in my T A. Since the 454 is in my truck...

 

what headers did you use im planning on putting a 496 in my camaro and i wanted to see if there were a specific header that i need or custom

 

This guy here pointed out a very good observation, and one that was never answered....DID you put dowels on?


VERY nice car/build by the way!!!

 

gosh you still dont have it done!? dont you know how easy this stuff is and how fast you can do it .... HA!

keep chuggin along, you're getting there.

 

Yes, they are installed. That's one thing my builder said was an absolute must esp with a big bore block because the sealing ring is so close to the bore that if the gasket moves at all I'm screwed.

I know right. I haven't worked on it in a while. I'm still waiting on fuel fittings so I can finish that up and then I need to figure out what i'm gonna do for headers. Everything else is pretty much done mechanically to get it running, the rest is wiring for the BS3 and gauges.

 

Cool. One of those things that I missed when reading the thread/looking at pics, so when the other member noticed it, I was like....hmmmmmm. I wonder if you did.
Anyways, glad ya did, that would have been a bitch
