  1. thats the moral of the story... id rather be out 300 bucks for cast ITMs from 1 fast z than 700 bucks for forged ross pieces from MSA. bottom line, i think under 350-400 hp if you beak one, youll probably have broken the other with your poopy tuning skills.
  2. very cool, kind of a gamble ordering a no name set of heads off of ebay, im curious, dr hunt, with so many established aftermarket heads why you'd even try these out?
  3. Also if you have the money to rebuild a motor, you've got the money to not rebuild it and go turbo.
  4. I dont think youll see over 200 to the wheels with aforementioned mods, but with your 4 speed and that 3.90 rear, it will be a fun zippy car. What flatblackz meant was instead of doing all that work you could retrofit a zx turbo setup on your motor and be even faster, also you'd probably be on the road quicker than all that machining. Use the search button at the top and try to find a list of all the datsun transmissions and thier gear ratios. If i remember correctly the 260 has the most aggressive gearing and coupled with the 3.90 and a 26" or smaller tire you'll have plenty of
  5. Continuing my train of thought from above, if I was building a 383 stroker and had the option of running 6 inch rods as opposed to 5.7's why shouldn't I? Why does the option even exist if its just "scuttlebutt" as my old buddy Colonel Potter used to say?
  6. Although i have the utmost respect for George Klass, and have used his accufab gear on almost every late model Mustang I've been able to (the ones we ran with e.f.i, that is), I have to respectfully say hes beating around the bush, on purpose. no one is debating that more cubic inches will make more power than less cubic inches, apples for apples. But what rod stroke ratio effectively does is allow for the other half of the horsepower equation to be magnified. That, of course, is RPM. Ask Mr Klass straight up if a higher rod stroke ratio decreases lateral pressure on the cylinder walls, and if
  7. I know theres alot of info on this particular subject, a guy on this board is currently going through the labors of installing a merc head from a much later L6 mercedes on his motor now. If you search for merc twin cam head I am sure his progressively updated thread will show up.
  8. Oh, and Raami, are those pistons "off the shelf" for the L28?
  9. This thread has grown into a pretty big pile of info on the topic, and its interesting to see how many different combinations are out there to achieve a similar goal... Thanks go out to all who contribute. Raami, what do you usually spin your motor to? What valvetrain mods, if any, do you have to support the extra revs?
  10. Also, KOM are those pistons from any vg30 motor? Or specifically a vg30de dett? Is there even a difference?
  11. Never heard of using the 138mm toyota rods, the vg30 pistons are the appropriate hieght for use with those rods? Very cool.
  12. well theres something i didnt know, i thought the higher the rod stroke ratio the better, whats all this 1.75 business?
  13. thanks for the input guys, youve been very helpful, as usual.
  14. well then i guess that begs the question, how much detonation resistance is evident with higher rod stroke ratios and is it in fact significant enough to build a street engine towards this goal?
