......................... big boys jumped on this ? I'm talking about, Crane, Comp. etc.

 

They probably dont want to have to worry about liability issues from unknowledgable people throwing them in with huge cams and destroying their engines

 

1.7 RR rule ! !

 

I just read your engine combonation, holy crap batman

 

Ehm, it's not possible to bore+stroke an LT1 to 427...(right?) so he must have something else in there?

 

4bolt LT-4 block, sleeved & filled w/ block filler

 

You ran a 12.1 @ 127 with a 1.7 60' and 438 RWHP??

 

ya - i double check my time slip

Track location: long beach, CA (now closed)
1/4mi: 12.18 @ 127MPH
1/8mi: 6.4@ 89MPH
0 to 60: 1.47sec
R/T: .8sec
alt: <30feet above sealevel


(EDIT)last time i ran was when i lived in LosAngeles
any one know of any good 1/4 mile tracks in San Diego??

)when i ran i had no idea how much RWHP, had 1.6roller rockers - maybe worth a few HP)

 

Something is not right. With a 127 MPH you should be deep into 11s if not high 10s with a 1.47 60 footer.

 

it says 0-60

 

double check your timeslip man, your 1/8 mile et and mph, doesnt match your 1/4 et and mph....something doesnt add up

just as a comparison my 1/8 is 8.1 at 89mph and my 1/4 mile was 12.5 at 115

1/8 to 1/4 difference:
for you 5.78 seconds and gained 38mph
for me 4.4 seconds and gained 26mph.....

and we crossed the 1/8 mile at the same mph.....

Comp already makes 1.7RRs.

 

back to the topic please. what are the advantages and disadvantages of running 1.7RR to 1.6 RR? maybe the disadvantages are too great, or by the time people want that much lift they just get a bigger cam. would 1.7RR do anything for stock motor/cam? would the valves still clear the pistons? Trey

 

the topic of "1.7 RR" has been discussed in detail in a thread a couple of months ago. try the search button

Probably a GPS system was used... That wasnt at the track.
