My car is street driven, tho and never drag raced. 285s, 315s. both spin in 1st too easily. The fun was the old tires, when only two needed replacement.. ohhhhh, the smoke!!

..... Hey Jamal ! ... Its been a few years but yeah , the Chevy 400 block I was using had some unfortunate issues that forced me to upgrade to the Dart Little M . From there I centered the build around using the factory LS7 titanium rods . That's why it wound up with 421 cubits ... It's not the fastest C4 on the Forum but it does haul *** ... Running N/A in Florida air its consistently in the 6.60's 1/8th mile and 10.50's 1/4 mile through a full exhaust and weighing in at 3600 # on the starting line . C'mon down , we have some of the best beaches in Florida , no offense ! .....

Be careful what you wish for, I just might come down and bug the **** out of you sometime again. I remember a few posts of yours about having the LS7 rods for a build. I knew you'd make it work and that's really cool. May not be the fastest out there but your average gearhead thinks running steel rods is as cool as it gets. Talk about an economical alternative to a $8,000 set from Crower. Some of the C6 Z06 guys mentioned issues with Ti dust shedding off the rods and scoring up bearing surfaces. I think it has something to do with the coating on the rods wearing off?

I have a 464ci (4.165X4.250) Dart iron eagle tall deck. It creates all sorts of issues. No oil filter pad on the block. You have to use a remote oil filter. You need an adjustable collar on the distributor, because it needs to go deeper in the block. Takes a special oil pan, the pan rails are spread .800". The cam is raised .391, so it takes a special timing chain set. It comes with intake manifold spacers that need to be machined and ported to match the heads and intake. And the intake manifold has to have the distributor pad machined from a 4 degree angle to a 5 degree angle. And to put it in a C4, the crossmember has to be notched for the bigger oil pan. But in the end I think it's worth it. It will accommodate a 4.25" stroke, and next bore size for me is 468ci, the final bore size is 472 CI.
