Thanks so much for your answer! Seems like its hard to find out which guides who fits in these heads :) Didnt find BJR racing on google, any website or something ? Anyone know ? :dontknow: Thanks all!! //Chris

Hi! Im into changing my valve guides in my Mopar Commando heads! Im using the P5249186 (2.08, 3/8 stem ) intake valve and the P5249188 (1.65, 3/8 stem ) exhaust valve. Both are 3/8 stem, the problem is i dont know what lenght to go with on the guide? I dont have the heads at home so i cant...

First off all sorry for the late reply, got alot going on right now ;) And a big thanks too all of you for laying your opinion, it really helps me deciding which way to go and it seems i may be aiming in the right direction. :D Any reason not to go with eagle rods? Not sounding negative ...

Sorry i should have written what i have and what is planned to be changed regarding the engine! The heads are already ported and converted to open chamber by the previous owner ( why they were converted i dont know i think he dindnt want more compression than 9.5:1 :? ) But the pistons...

I have just taken the enginge and trans out of the car for a major look-trough and upgrade. Im going to change to a roller cam from hughes engines, eagle H-beam rods and possibly new pistons. The trans will get a new 3800 stall converter from Dynamic and an overhaul with new clutches and so...

Didnt really know about bushing so thanks for the reminder ;) Who sells them?

Anybody using a Hughes Engines roller cam? Any thoughts about them, quality, performance etc ? Any difference from say Comp or Cranes roller cams ? Im gonna go for a solid roller cam! :) Thank you! :)

So they are to put on engines that might be to small for the carb ? Or is the otherway around ?

What is it when a carb has a annular discharge ? And what is it good for ?

Im running TTI step headers! Aint anyone running a girdle ? Im thinking of one as it seems like a priceworthy investment for the bottomend :)

What oilpan do you guys with 340/360 strokers use? I still have a stock pan with a lousy pickup but a melling pump. Im thinking of upgrading the pan and pickup but im not sure what to go for! Moroso or Milodon or something else? Also anyone running a Hughes engines main girdle? How is...

Gear is 3:91 at all times except for long distance traveling ! Tires will be M/T Et Street 10 ½" wide and 27" tall! :D

Does anyone use these lifters? I have read alot of good stuff about them, but are they worth the price you have to pay for them? Heard they were reusable if you change the cam? Just bought a new cam from hughes engines with 260/264 @50 lift with .587/594 " lift with 1.5 rockers. Does...

Im curious about which of these manifolds would do best for my setup, i currently have a Mopar M1 ontop of a pair of ported mopar commando alu heads that have been ported a little ( 277cfm at .600" lift ). Its a 416 stroker. I have just bought a new cam for the engine with 260/264 @50 lift with...

Is there any drawback in having a high idle ( except for the noise ) ? More wear on components etc? I like having a little high as it tends to send the hole car in wobble when standing still with lower idle rpm! The lambda meter seems to be very interesting as a tool to setup the carb, read...

But for the carb, does the demon perform better than the avenger but the demon is more work to tune? Me and my father are thinking of investing in a lambda meter for tuning the carb! Would this save alot of hassle when working with a demon or would it be wiser to go for a avenger right away ...

Thx for all your answers! I think i figured the vacuum thing out! I looked more at the advertised duration than at the @.050. And then also that the idle rpm is so high, i tested to lower it to about 700-800rpm and the vac. dropped to 4-5 ipm! :) Would there be a performance gain worth the...

Im not really sure what it was when the car was in gear as my friend did the measurments but i think it was 12-13 ipm at 1000 rpm. What should it be ?

The cam is V 9215 Part # 2-000-5. I cant find it at comp cams page so i guess they dont make it anymore? How much vacuum is, so to say, wanted in a streetable car? Im not so good at this as i only have begun to understand engine buildning, but im trying to learn! How much agressive cam...

Hi! I have a question about vacuum! I just got help from a friend to measure the vacuum on the engine. The thing is we got 15 inches per mercury! I think thats alot and i wonder what may cause it!? The engine is a 340 stroked to 416cui. The cam is a comp cams mechanical cam with 280/300...

Heads are Mopar performance stage1 alu heads that have been converted from closed to open chamber. Intake is Mopars M1 single plane, carb is a Holley 750 and exhaust is TTi step headers and a 2½" system with h-pipe. The rods have ARP bolts in them. But how about if i change to say Eagles...

Hi! I recently got some info on the engine that sits in my car that i bought last year! The engine is a 340 stroked to 416 with mopars 4.0" stroke crank. The crank has been cryonized (spelling?), what is this and what does it do? The rods are stock rods that have been shot peened and...

Hi! I just have a question about my camshaft! Im running a 340 with solid camshaft, i dont have the specs on it! I had the engine out this winter and checked it and i found out the timing chain lacked oiling. So i fixed that the stock way, one of the bolts that hold the camplate should have...

No i was wrong , the center carb is Mopar competition mechanical "These specific carburetors were then modified and converted from vacuum secondary to full mechanical in the form of Holley List 4782/4783s which MOPAR offered for competition uses thereafter." Kinda cool :)

Hi there Duster340, im very much alive and well :) I never saw your car on Wheels Nats :( But then again i know what you look like , like the big pic of you holding your tti headers in evey Wheels Magazine :D I got help with the carbs on another forum , turns out that i own a set of two...

Hi! I just found three holley six pack carbs in the basement that my dad bought 20 years ago. I want to identify them but i cant find any good info on them, what car they are for and when they were made. Outer carbs have list nr 3659 stamped and date is 2003. The center has list nr...

Thx :D I didnt build my engine as it was sitting in the car when i bought it but here are the specs i know! Original 340 block 0.030 bored Heads are MP alu heads converted to open chamber by Hughes MP M1 intake Holley 750 MP 4" cast crank that has been cryod Original shot peened and...

How much do you guys with 340 stroker combos push your engines ? I´ve got a 416cui in my Duster with a 8 3/4 with 3:91 and it feels scary too go over 6k rpm. I have not tried it on the strip yet but i intend too! Does stroker combos tolerate as much rpm as a 340 do ? //Chrippa
