Ive got a 408 with eddy heads . The porting is stock but they have larger inlet valves 2.08 from memory . It dynoed 515hp and 535 ftlb.its running a 750 holley and dual plane inlet with a howard hydraulic roller. Ive ran 11.2 at 120 in a street car through a 727 and 3.9 gears.i would dearly love...

yep rack and pinion , i will keep the sump mods on hold until its all fitted up .Then see whats what

heres a couple of pics and the dyno chart. We ended up with a 750 double pumper as the builder didnt think a vac sec would be any good on this engine . pretty good numbers and lots of torque which is what i was after . This was without using a fancy electric water pump , airgap manifold or even...

the 408 is together and running , should get a look at it tomorrow on the dyno . Even with the dual plane and my crappy try y headers it pulled 512hp and 525ft/lb im happy with that

well things are slowly coming together , the bottom end is buttoned up .The heads are getting the bigger valves fitted , so shes on

correct , the part is a 710665-10 Thats a roller hydraulic , and the duration is almost the same as the one you recommend ben

thats right , itll be mainly a street car , with only the odd run at out 1/8 mile strip a couple of times a year. Outright hp is not really the goal , being able to do a rolling burnout is far more important to me ! The dual plane may hurt top end hp a little but if it gives me more twist down...

there will be nothing wrong with the machine work , im confident of that so thats good news.I hate to say it but he mainly builds chevs and fords but he has built mopars before so I hope we both get a surprise when it goes on the dyno .

No a heated inlet isnt a big deal , my 360 didnt have one and besides i dont drive it much in the winter. Theyre just a RPM edelbrock , if theres more than 1 model then im not sure.The engine guy is going to take the inlets out to 2.08 , which in his opinion is easier and cheaper than going...

ive already purchased the rockers and heads so theres no turning back on them . The heads and rockers were second hand and had done about 1000 miles and were set up with a solid roller prior to me buying them .The engine builder has measured up the lift etc and says the springs had already been...

the whole engine was designed to see a max rpm of 6000-6500 . I was looking for more torque than max hp . As with most things I guess theres some conflicting stories as to weather a single plane will produce more power than a dual plane at these revs.I think if it was to see 7000 i might agree...

Hi , after pulling my 360 i found the bores oval and alreadty 40 thou over .I had tossed up the idea of building an engine myself but with a decent mopar friendly machine shop a long way away I decided to let an engine builder build the lot. Im In Australia and have ordered most parts either...

what about the mopar performance 440 commando small block? is anyone running one of these? ben
