1984 SVO: I'm looking to break 300 wheel, I've got about $3,000 to spend but cheaper is better obviously.
Things I've already got: - pimp ecu (2015 version) - VAM to ACT conversion - large FMIC - 255lph fuel pump, was told it was but not 100% sure - holset hx35 - stage 3 - 6 puck spec clutch - gnari cast manifold with 38mm external wastegate port - emusa 38mm external wastegate
Things I've got on my list to buy: - full bearing kit/seal kit, general maintenance (engine is stripped to bare block) - CP pistons and ring kit - crower sportsman rods - ARP main bolts - ARP rod bolts - ARP head studs - 1035 head gasket - deck block and head surface - BoPort stage 1.9 cam with beehive springs - Delphi 93lb/hr @55psi injectors
Not really looking to do any porting work if possible, shooting for 25-27psi on E85
From my automotive experience this is easily obtainable but I've been told these engines in particular don't like to make power without some intake, head, and exhaust porting work. I've searched through the proven combos list but a lot of them don't list a HP or TQ
Also would like to know if doing a coil on plug or E-DIS conversion is worth it/easy. I've stripped 2 dizzy gears and replaced the aux shaft already so don't want to be left stranded again.
Save your money on the ARP main and rod bolts, head bolts aren't really necessary either but can be used if you want. Crowers come with the bolts needed to use with them. Main bolts are for 600+hp builds.
The e85/high boost thing will "cover up" your lack of porting. You'll likely blow past your hp goal at that boost level.
If you're wanting to get rid of the dizzy gear then the "easy" way to do the coil on plug swap is not possible (our CAS setup). You can certainly add a cam trigger and cam sync and do it that way though.
I'd not suggest an EDIS or DIS setup unless you've already got all the parts to do so.

Can the head gasket handle almost 30psi with the stock bolts? ive blown 3 head gaskets in the past 3 years. 1st time was a boost controller failure, blew at 25psi. 2nd was 22psi. and 3rd was 18psi. That was the biggest reason i wanted to go with the head studs. (should note that the first 2 were on the same engine. 3rd time was an engine in unknown condition)
So CP pistons. crower rods. and a 1.9 cam hitting 25/27psi on e85 should be enough for well over 300? i think thats what i got from your reply.
Headgaskets blow from detonation or other tune related issues (too much timing, too little fuel, too much boost, etc.), not from too much boost. Proper torque procedure (and re-torque after a heat cycle for anything other than the 6 point felpro bolts) is way more important than whether it's bolts or studs.
Yes, a bone stock longblock will make about 400hp at 30psi (with a big turbo and proper tune) so an engine with some mods and less boost should be well over 300hp if things are right.
