Thanks guys!
Yeah this engine is going in a 1940 Ford....had quite a few different engine combos in this car over the years...
Yes I flowed the heads...dont have the data sheet in front of me..but the intake manifold picked up the cfm about 12-15 when it was bolted on...When I flowed the heads w/ out intake I didnt use clay or a port fixture. The heads went over 400 @.700 with intake manifold bolted on. Not a real big runner.
For N20...Id like to throw 3 hundo at it...going to do the NA thing for a while first.
Heres a few pics from the shop..
When the '40 used to be sb2 powered..
The Z06 w/ 16" hoosiers
1st pass at the track w/ new hoosiers...broken intermediate shaft..lol
427 LT5 cam degreeing...
My buddies ride.Skinny kid car w/.Sonnys power!

If your building a 7K RPM 427 screamer, that'll be running a 300 shot, why in the hell would you cheap out on main and head bolts?? That just makes no sense at all.
Forget about lifting heads, just think about main cap shifting.
Your building a bad *** setup, yet bolting it together with junk bolts..
I mean no disrespect, but based on your other cars, your not hurting for cash, nor are you lacking in the knowledge dept. The extra 400 bucks can mean the difference between pushing water and steam cleaning a piston, or a solid long lasting motor..

Jeff...appreciate the heads up!
all ideas are appreciated!I have sprayed more than 300 with stock bolts before on Ls1....maybe Im just lucky?
I really think the arp stuff is overkill...I hear you about cheap insurance on the bolts/studs. I really dont think its needed...just from my experience.
On the all out race hardcore stuff I have, I use them. Besides the ARP stuff gets really expensive quick!!!I went really cheap on some parts of the engine...and spent the green on heads, cam, and pistons...

OK guys got the car done midnight on Thursday for Pinks All Out..
didnt have time to get the N20 on the car but Im very happy with the all motor 419 CID LS7..in the all steel original frame '40 Coupe.
Installed a wideband A/f ratios were good with the lil Davinci carb...13.0 all the way through!
Didnt have too much time to dial it in but it went 10.4 @129 all motor...mile high air for the day was 8000+ feet DA..Need to get this little coupe at sea level..real curious to see what it can do in some lower elevation.
60 foot 1.41..Heres some pics from the shop and track this weekend!
Broke her in on Joe Gibbs oil...wanted to break it in fast..
VERY VERY happy with this low dollar engine...got to love LS power! There was a lot of cars there in the 10 sec range...the pinks guys picked a slower field...12.0
This things goona be an animal with some N20..
looks like the guy next to me was makin a sandwich before they took off cant see em in the pick right off the line...LOL
