Thanks Doug I was able to contact him the next day and your right he is going well and more than helpful as usual, big in big out is on it's way.

Yes mate I know, said it tongue in cheek 

Great advice you can't argue with the facts on the carb. I am running beehives on the heads now after you guys advised and they fixed the valve train problems I had. I will stick with a hyd roller and use them, I have them installed at 150 seat /375 open will that be ok for pressures once I check bind etc. What do you think of this grind it's a comp 236 and 242 with 636 and 634 lift 112 lobe sep
Would that work with my top end? I didn't mention I'm using fpa tri-y and have a 7 quart baffled sump and windage tray, restrictors are in the heads I'll do the oil mods as per Barry's book as I did on the old block

A conrod bearing on my 390 has failed and it's .060 over now and is not a suitable starting point for stroker build and I don't want to spend any more money on what will never  be an engine that will suit my aim. Have found a standard bore block that should be suitable if it checks out ok. My aim is to spend plenty of time on the strip with occasional cruises in between. I have a 64 Gal f/back with 3.7 gears ,toploader, caltracs, 31 spline axles and 28 inch M/T et streets. The parts I will be using off the 390 are 60069 Eds with standard valves with some porting and blending matched to a RPM Performer, Harland Sharp needle rollers and I have been using a comp hyd roller D 230/236-L 521/529.Ineed advice on cam and compression selection [piston style choice] for the best combination for a heavy car. I am a bit disappointed with the roller lifters as they are a little noisey after only relatively low miles and would love to fit a solid flat tappet something like a comp 284b-8 if that would suit, but I am dead scared of wiping a lobe and having to tear it down again. I would like to be able to run low 12's consistanly or better if me and the suspension are good enough. I will upgrade the trans to a big in and change to a 3.9 or 4.11 as required. Ignition is msd mech advance and 6al box. Some estimates on tqe and hp with different combos would be appreciated. I will be in touch with Survival for assy supply as it will be ready to go. I forgot to add that the heads are 67cc.Thanks in advance, Rob.

Thanks for the replies, I won't be taking anything for granted in the future, I'll be assessing the individual parts supplied in any kit I use.
As this was delivered directly to the machine shop I'm pretty disappointed in him as well(spent plenty there over the years-as well as recommendations). After several emails to comp they tell me I need better springs ,go figure, so I let them know my thoughts. They are telling me the same as you guys, the supplied springs are even less than advertised. I'll probably have to save a bit and go with the beehives. The x pipe is a Summit product and the pipes are coming off for a dyno run next time I'm off shift, he's not charging me for this one. Thankyou all for your tech expertise, it would be easy to dig a bigger hole without it.

Hi Todd, I'm at the Sunshine Coast QLD mate. I tried a750 dp on one run and made 5 hp less , I bet this something so simple that I can't see the forest for the trees. A/F ratio's were simlar , no apparent leaning off. When I get a chance I will install original distributor and see if there are any variations.                 Thanks Rob.

Thanks for the replies,the a/f ratio stays in the mid to high 12's so I don't think it's running out of fuel either, I just had a look at the plugs and not as clean as I would like to see a bit dark and this car runs perfectly ,great start up ,crisp idle, no flat spots , plenty torque and acceleration. Just hits the wall when you really want to push to the next level so I'm wondering about the rotor phasing etc. There's no scope on this dyno , so I may have to go to another.

Sorry ,I probably didn't explain that properly it will continue to rev past 4900, It's just that the power drops off dramatically and you are going nowhere. The rev limiter is set at 6200( won't need that the way I'm going). Pretty sure fuel lines are 5/16. The carb is a 770 street avenger and did experiment with p/valves and jets on the dyno ,also used a 750dp and ended up with slightly lower readings all in the same rpm range. I have also made sure that msd supply is actual battery voltage and not ballasted.
