Andy's Auto Performance 388 (pictures)
 

The motor is in the car and will be going to Irwindale this Thrusday for some test and tune runs. The 6.0 heads flowed 352 cfm @.600" intake and 240 cfm @.600" exhaust <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />

Enjoy....... <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />

Looks good. I'll have to come out Thursday and show you what an all bore can do. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Haha Terry, add 400lbs to your car and T-56 and I'll be glad to line up with you. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> The Rev 1116 dual springs are more sturdy than my old 987 dual springs, I haven't heard of any failures with these springs unlike the 987's.....

Re: Andy's Auto Performance 388 (pictures)
 

I am in the process of putting 987 in my heads. What problems have you had with them? Thanks.

Re: Andy's Auto Performance 388 (pictures)
 

REV duals with 242 duration and .612 lift here. No problems! Not sure which REV's though.

Re: Andy's Auto Performance 388 (pictures)
 

I didn't have any problems with the 987's per se. but my mechanic did say i was getting valve float on the top end because of them. I have heard of stories of 987's breaking, not so much with the rev 1116 duals.

Re: Andy's Auto Performance 388 (pictures)
 

Looks good...is that a dry sleeve setup? Also, wouldnt 4.125 bore by stock stroke (?) be a 387?

JPR is doing an all-bore 387 for me, so Im in a similar boat, with the engine ready for the dyno hopefully by this weekend.

I seem to have heard the opposite. There have been several people on this board that have broken the Rev springs. For awhile, I had heard of 3 or 4 of them breaking all from different people all in the same week. They were all running relatively small cams also.

I've never heard of a 987 breaking personally.

Re: Andy's Auto Performance 388 (pictures)
 

What did those heads flow on a 3.900" bore?

Re: Andy's Auto Performance 388 (pictures)
 

Well I think we all can agree that there is no "miracle cure" valve springs for the LS1, I went with the spring that I think best suits my setup. EZss, I don't know that the exact mathematical formula to come up with the CI of an engine but I always thought that a 4.125 bore x 3.622 stroke was 388 cubic inches, I could be wrong though. Concerning the sleeve setup I know that it is an LS6 block with non-Darton sleeves. My buddy Micah has AAP 6.0 heads on a stock motor and his heads flowed very similiar to mine. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

My car runs a lot faster than your setup is running on a six speed, and Jason knows how to drive too. I have more mph and a lot more weight (still my daily driver) so get lost and stop trying to compare apples to oranges.

I was just making the point that huge head flow numbers don't mean the car will haul ass or make much power. It just means the the headporter knows a lot of flow bench tricks. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Yeah and 10.30s if Mark was driving... <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: Andy's Auto Performance 388 (pictures)
 

*Sigh* What part of comparing like cars is so tough for you? Those same heads and cam are making 118mph traps (2mph slower than mine) on a six speed car that's 200lbs lighter than mine. Sounds like a "magical" set of heads to me. <img border="0" alt="[jester]" title="" src="graemlins/gr_jest.gif" />

Re: Andy's Auto Performance 388 (pictures)
 

Hey I can only speak for my car but it does take some work to get going that quick. Its not like you bolt on heads/cam and run 10s. You need gear, slicks, a good exhaust, good tuning, and some other tweaks to get there.

My point is big head flow numbers are not necessarily part of that equation. This is just my $.02 but I wouldn't use 6.0L heads on anything but a 9:1 blower/turbo car.

Re: Andy's Auto Performance 388 (pictures)
 

I dunno Terry, Jason seems to really know what he's doing. Granted he needs a rear end and a tire (badly), but that's not going to give him 9mph.

</font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">He needs a lot of work but he'll get there. The reason his MPH is way down is because of 3.42 gears. When I went from 3.23s->4.10s I picked up 3.5mph! Running on slicks will help his MPH even more. An underdrive pulley will add another MPH. In addition I think there is something wrong with his lifters, his engine ticks really loudly at idle. I think he has a clutch issue as well.

He'll be in the 122-3mph range as soon as he adds gear, slicks, and takes care of a few little things. As far as I know with his rollbar/street tires he is the same weight as you.
