    360->408 Builds at High Altitude Help!

    Hi everyone! I am mapping out a 360->408 stroker build in Denver CO at 5500 feet. I have been playing around with Dynosim6 and the max horsepower I can seem to get at that altitude is ~450 HP naturally aspirated. Has anyone built any 500+ HP naturally aspirated small blocks at altitudes this...

    Kinsler ITBs for 360 SB

    I am wondering if anyone has used the Kinsler SB Mopar intakes on their A-bodies. I am mapping out a build of a 408 for a Plymouth Duster and am curious what challenges people have had with ITBs. How are hood clearances? (I am thinking I would have to 3D print ram tubes to make it work) How does...

    360 LA Main Bearing Oil Holes Look Funny?

    Hi Everyone! I just picked up a LA 360 block for $400 (hopefully I didn't over pay too much). After getting it home I noticed that there are 2-3 holes drilled into some of the main bearing oil holes. Is this stock or did someone drill into it? If this is not stock how will it effect the blocks...

    Am I an idiot for wanting to boost a high compression 318?

    I have pretty much zero experience tuning outside of playing with timing a little bit. I would take the car to dyno and to someone with more experience to help out. I was eyeing this company in Denver: Finish Line Automotive & Performance

    Do you have any sources you would recommend? What am I misunderstanding?

    So with getting a Holley Sniper I was also going to get an EFI fuel tank with 340 LPH from efi system pros (see link below). Do you think that will be enough for the super charger? Efi system pro recommended Holley 550-540 Sniper XFlow EFI System Silver for this application EFI Fuel Tank...

    That's what I was thinking to! I am currently 2 PSI under atmospheric conditions at sea level. So if I go for 4 PSI of boost I'll really be only 2 PSI over sea level atmospheric conditions

    The more I type the more I think that's what I want to do. Just might be a few months before I order the parts. I'll take things real slow and start off with a larger pulley that what the super charger comes with. I'm not going to be racing the engine a lot

    Pretty sure the fuel return line and emissions cannister and stuff are removed and capped. I like the idea of trying to insulate the lines and getting the gas to recirculate again. I actually do have a pair of 360 heads on the engine. My dad always referred to them as police engine heads but I...

    Even if I was running low boost? Like under 4 PSI? I am also at 5200 feet elevation so the atmospheric pressure is around 12.5 PSI at sea level its 14.7 PSI so 2 PSI of boost would just get me back to atmospheric pressures

    Am I an idiot for wanting to boost a high compression 318?

    Oh I agree but then I have to pull an engine and I don't want to do that ha the parts I am dumping money into could (hopefully) be easily transferred to another engine. This 318 is definitely not a pristine block. Pretty sure it was 200K+ mile engine when I got it about 12 years ago. (my dad got...

    The engines already built with 10.3:1 compression and I want to get some more horses out of the engine easily. That's why I am considering boosting with a super charger

    Am I an idiot for wanting to boost a high compression 318?

    Hi All, I have a 318 in a 1975 Duster with the following specs: 10.3:1 static compression, 4 barrel dual plane air gap intake, Clevite hydraulic flat cam w/226 duration and 0.453 valve lift, headers, edelbrock carb, stock bottom end, some head work I did on my own, and at 5200 ft in elevation. I...
