@Inertia tried that and the valves have no wobble obvious to the eye. I think they're straight. @cookietruck see attached image of the cam specs. It's a clevite camshaft.

Hi All! Just took off cylinder 4s valves and have a picture attached. That was the cylinder that had terrible compression. They seem to be in good shape and straight when I put a straight edge next to them. What are thoughts on this? It is looking more like a timing chain skip from my...

The Saga continues!!! I got the passenger head off yesterday and it looks like I was wrong about the valves hitting the pistons. Cylinders 2, 4, and 8 show signs of the intake valve hitting the pistons. (See pictures) I haven't taken apart the head yet. A couple questions: Is this enough...

@AJ/FormS, thank you for all the by the ways. The car has sat without running a lot over the years. My dad and I rebuilt it together then my dad passed away in 2016 and then it sat in my mom's garage until 2022 only getting started about every 6 months. I swear we had built it to be closer to a...

@GTX JOHN I did a compression test and here is what I found: Cylinder 1: 102.5 PSI Cylinder 2: 120 PSI Cylinder 3: 105 PSI Cylinder 4: 15 PSI Cylinder 5: 110 PSI Cylinder 6: 115 PSI Cylinder 7: 112.5 PSI Cylinder 8: 115 PSI The real kicker here is that I checked Cylinder 2 and 4's...

TWO BROKEN PUSH RODS Saga! Hi all!! I have a 318 in a Plymouth Duster I rebuilt with my dad about 15 years ago. The car/engine hasn't been driven very much, probably less than 1,000 miles. So the complete back story: A few months ago I noticed that cylinder two (front most passenger side)...

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...

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...

Thank you!! @Rat Bastid and @Jadaharabi

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...

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

Yes I'm an idiot? Damn...

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

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

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...
