    Engine and Trans removal together?

    I do mine from the top almost every year now. Pull it all to do trans work as well. You can just tie or wire the headers to the inner fender, pull the distributer, front pulley , the starter, oil filter , pull the rad, drop the center link , you can get away with just the track bar but I...

    Guess my Hp and Tq

    If you want mega valve lift you might have to go with a 1.65:1 rocker arm. But I'm talking over .650 or so lift. (+/-) You will be happy with your build from looking at your set up. These 408's make awesome Trq down low and hold onto it for a while.

    Guess my Hp and Tq

    That's what I thought . We put just about the most we could into that small block without having to go to an R3 block and Indy heads. I was disappointed in the numbers at first but those are just numbers , it feels like it should be more....especially the Trq . I'd rather tell ppl it's lower...

    Guess my Hp and Tq

    515 hp 508 Trq 6300 rpm/ 4200 rpm. I just finished my build in the spring with bigger intake valves (2.08) different cam . solid roller, (huge lift) 1.65:1 rocker arms, bigger carb and more flow on eddies all around with matching ported victor and with crappy 1 5/8 headers for the dyno, got...

    408 blueprint motor 445 hp

    I'm curious to know the price of one of these 445 hp 500 ftlb engines with a warranty. They are probably great if your into the restoring and re selling business. Sounds very similar to my last 408 that was built by a legit builder, one of the best I know about and that engine came apart with...

    408 blueprint motor 445 hp

    I say support your local machine shop. The reason engine shops hardly exist anymore is for 2 reasons. Import junk and large companies pushing the small guy out useing fast pace lines and mass produced parts . Support the small guy , JMHO

    408 blueprint motor 445 hp

    I would just have one built. 450 hp will not be hard to accomplish using a 360 or a 340 based block. 2.02 Intake valves in minor ported cast heads and a good forged rotating assembly and your there. You don't even need much compression. Maybe 9.5:1 would be fine. Then you know what is in it...

    408 blueprint motor 445 hp

    Check out car craft magazine. I copied a 416 build they did at IMM engines. I followed every part on the site right down to the carb and the headers. Only difference I did,bored to a 408 and I grouted the block, my compression ended up being 10.89:1 compression . Pump gas engine. The...

    Proper engine placement?

    What is the correct offset that the engine sits to the right side. I thought it was 1 1/4 -3/4". I'm sitting around 1 3/4 maybe even closer to 2". The mounts were built from previous owner. Everything lined up on instal just fine, (trans,headers, center link and steering)kinda wondering what...

    408 carb question

    20mpg. Wow. I dont get that in the gf's civic. I didn't intend on opening up the big carb small carb argument. In a way I'm on both sides of the story here. But still believe there is such a thing as over carb. I'm gonna have to pull the valve cover and roll the crank to a dial to see what I...

    408 carb question

    I wish I knew exactly what cam is in it. When I say mild I kinda mean fairly stealthy. Idles hard / drops hard . I should get ahold of the guy that had it built. (Lost contact) , what I should do is just get a 750 and see what happens. Can always sell one of them or keep it like the rest of the...

    408 carb question

    I have a 408 with stock J heads, un ported and mild cam. Currently have a 600 ede carb and it works fine for now. To tell you the truth I haven't tuned anything quite yet until I'm done with the car so im not entirely sure how it will act after tuning. Wiring harness and full MSD ignition is now...

    408. best oil for it

    its more like 1/2 ltr every 4 hrs now, the way it is slowing down mellows me out. im gonna go with a 15W30 and see how it likes that. I get a feeling from reading on here its more of a self prefrence on what oil to use, some are useing 15w40 and some 5w30. seems like it doesnt matter unless...

    408. best oil for it

    it is using maybe 1 lt every 2-4 hrs. but it has seemed to slow down a bit . I did fix a leak on a valve cover that was a bit loose and thought that was the issue but still disapearing a bit.

    408. best oil for it

    I have been taking it easy on it for that reason, i was just worried about the oil disapearing. If it was initialy broke in with a 15w 40 am i harming the engine by running a 10w30? For some reason i remeber the guy saying something about 15w 40 but with no paper work or contact with this guy i...

    408. best oil for it

    Is it possible that 10w 30 royal purple is to thin for my 408 with weisco pistons/rings Could i run 15w40 RP oil? I find the 10W30 disapears slowly and slight exhast smoke. What are the effects of runing a diesel engine oil? If any.
