Recommended Posts

hey guys,

 

my friend paul finished the build up of his latest motor for his 240 drag car.

 

pics of the engine and car: http://www.imagestation.com/album/?id=4291962855

 

the first 20 pics are of the 377 that's currently in my car after it was initially built for the drag car. pic 21 starts the new engine pics.

of 4 runs at 1/8th mile track in eatonton, ga on sunday, july 22:

first and worst: 7.15 seconds at 100 mph

best and last: 6.85 seconds at 102 mph

--> lots of wheelspin on all 4 runs; would have run more, but it was just too hot out there....

 

best 60' time: 1.55 seconds

 

best 60' time on 377 was 1.44 seconds, so there is still room for improvement.

 

i am curious what desktop dyno says about hp and torque. if anyone could run the numbers, it would be greatly appreciated.

 

thanks :D

hey guys,

 

paul appreciates the complements :D:D

 

owen, i'll try to get some shots of the headers when i get back from my business trip to memphis. the headers are s&s 1 3/4 full length headers, the same as msa sells. they are within a 1/4 of an inch of the steering arm. when they were coated, paul had the shop cut the collectors off and weld on turn downs. the new turndowns basically dump the exhaust right behind the front wheels.... very very loudly, hehe.

 

he used the same headers on his '72 car and found that they basically dump right into the firewall as they come from s&s. this set was a little different than the set on his '72, though. on his '72 he had dual 3" exhaust, but the exhaust shop had to do some weird angling to get from the header to the straight pipe. if the primaries came down about 2 more inches, they would be perfect for the scarab kit. i understand that they may be a little too low for the jtr kit, though. i plan on using s&s when i convert my '73 to jtr, so i'm a little curious about ground clearance.

 

mike kz, you're invited any time... when i get back from memphis, that is. paul and i are looking forward to seeing your car in person. paul got a narrowed 12 bolt for the drag car and wants to see yours to see what's involved in that swap.

 

jt1, the vic jr's are straight out of the box. a friend wanted to port them, but we thought they would be fine as is. paul's already planning another 377 build, using the 64cc vic jr's.

 

thanks again,
